Network config details

Description of problem:

The output of 'bridge -json -details link show' generates invalid JSON for the given network config and status;

====
[{"ifindex":9,"ifname":"bcn1_bridge1","flags":["BROADCAST","MULTICAST","UP","LOWER_UP"],"mtu":1500,"master":"bcn1_bridge1"},{"ifindex":10,"ifname":"ifn1_bridge1","flags":["BROADCAST","MULTICAST","UP","LOWER_UP"],"mtu":1500,"master":"ifn1_bridge1"},{"ifindex":11,"ifname":"ifn1_bond1","flags":["BROADCAST","MULTICAST","MASTER","UP","LOWER_UP"],"mtu":1500,"master":"ifn1_bridge1","state":"forwarding","priority":32,"cost":100,"hairpin":false,"guard":false,"root_block":false,"fastleave":false,"learning":true,"flood":true,"mcast_flood":true,"mcast_to_unicast":false,"neigh_suppress":false,"vlan_tunnel":false,"isolated":false,{"ifname":"ifn1_bond1","vlans":[]}},{"ifindex":12,"ifname":"bcn1_bond1","flags":["BROADCAST","MULTICAST","MASTER","UP","LOWER_UP"],"mtu":1500,"master":"bcn1_bridge1","state":"forwarding","priority":32,"cost":100,"hairpin":false,"guard":false,"root_block":false,"fastleave":false,"learning":true,"flood":true,"mcast_flood":true,"mcast_to_unicast":false,"neigh_suppress":false,"vlan_tunnel":false,"isolated":false,{"ifname":"bcn1_bond1","vlans":[]}}]

This generates the error in one parser of:

unexpected end of string while parsing JSON string, at character offset 625 (before ""ifname":"ifn1_bond1...")

I verified that the JSON is invalid with http://json.parser.online.fr/ (see attached screen shot).


Version-Release number of selected component (if applicable):

v5.3.0


How reproducible:

100% 


Steps to Reproduce:
1. Configure a machine with 6 interfaces as shown in the network config attachments.
2. Run 'bridge -json -details link show'
3. Validate the output JSON.

Actual results:

Invalid JSON


Expected results:

Valid JSON
