Description of problem:
when the system-id changes, the table chassis_private doesn't clean the old information

Version-Release number of selected component (if applicable):
# rpm -qa|grep ovn
ovn2.13-host-20.06.2-1.el8fdp.x86_64
ovn2.13-20.06.2-1.el8fdp.x86_64
ovn2.13-central-20.06.2-1.el8fdp.x86_64


How reproducible:
always

Steps to Reproduce:
at first,set the env as below:
#ovn-sbctl show
Chassis hv0
    hostname: dell-per730-57.rhts.eng.pek2.redhat.com
    Encap geneve
        ip: "20.0.10.26"
        options: {csum="true"}
Chassis hv1        ----------------this name is hv1
    hostname: dell-per730-19.rhts.eng.pek2.redhat.com
    Encap geneve
        ip: "20.0.10.25"
        options: {csum="true"}

then config the ls and ports.

change the system-id:
ovs-vsctl set open . external_ids:system-id=local

then,
#ovn-sbctl show
Chassis hv0
    hostname: dell-per730-57.rhts.eng.pek2.redhat.com
    Encap geneve
        ip: "20.0.10.26"
        options: {csum="true"}
Chassis local        ----------------now the name is local
    hostname: dell-per730-19.rhts.eng.pek2.redhat.com
    Encap geneve
        ip: "20.0.10.25"
        options: {csum="true"}

then check the chassis_private table,there are three items:
# ovn-sbctl list chassis_private
_uuid               : b612ba1c-5434-4864-be37-02fa68a056e1
chassis             : fd1b04b6-972c-4dce-b24e-7a0ac31dcf94
external_ids        : {}
name                : hv0
nb_cfg              : 102
 
_uuid               : 70346152-cece-44b9-b39c-dbf0f5845e35
chassis             : d3831b51-8ddd-4b4c-8844-0a225e738f36
external_ids        : {}
name                : hv1            ---------------this item should be cleanup
nb_cfg              : 0
 
_uuid               : 58628c1f-b623-4a98-af4f-821a9d101aba
chassis             : d3831b51-8ddd-4b4c-8844-0a225e738f36
external_ids        : {}
name                : local
nb_cfg              : 102


but we can see the table chassis clean the old item:
# ovn-sbctl list chassis
_uuid               : d3831b51-8ddd-4b4c-8844-0a225e738f36
encaps              : [bc8869d2-130a-4754-ac51-52dd05576c1e]
external_ids        : {datapath-type="", iface-types="erspan,geneve,gre,internal,ip6erspan,ip6gre,lisp,patch,stt,system,tap,vxlan", is-interconn="false", ovn-bridge-mappings="", ovn-chassis-mac-mappings="", ovn-cms-options="", ovn-monitor-all="false"}
hostname            : dell-per730-19.rhts.eng.pek2.redhat.com
name                : local
nb_cfg              : 0
other_config        : {datapath-type="", iface-types="erspan,geneve,gre,internal,ip6erspan,ip6gre,lisp,patch,stt,system,tap,vxlan", is-interconn="false", ovn-bridge-mappings="", ovn-chassis-mac-mappings="", ovn-cms-options="", ovn-monitor-all="false"}
transport_zones     : []
vtep_logical_switches: []
 
_uuid               : fd1b04b6-972c-4dce-b24e-7a0ac31dcf94
encaps              : [2bd0a98d-71f0-45eb-9537-33dc7f80634f]
external_ids        : {datapath-type="", iface-types="erspan,geneve,gre,internal,ip6erspan,ip6gre,lisp,patch,stt,system,tap,vxlan", is-interconn="false", ovn-bridge-mappings="", ovn-chassis-mac-mappings="", ovn-cms-options="", ovn-monitor-all="false"}
hostname            : dell-per730-57.rhts.eng.pek2.redhat.com
name                : hv0
nb_cfg              : 0
other_config        : {datapath-type="", iface-types="erspan,geneve,gre,internal,ip6erspan,ip6gre,lisp,patch,stt,system,tap,vxlan", is-interconn="false", ovn-bridge-mappings="", ovn-chassis-mac-mappings="", ovn-cms-options="", ovn-monitor-all="false"}
transport_zones     : []
vtep_logical_switches: []


Actual results:
the old item is in the table 

Expected results:
the old item should be cleanup
