Description of problem:

The operation of detaching a single iSCSi domain with a single host on DC, prompts a connection to ( $NUM_OF_SESSIONS -1 ) every time.

Before detach, the connections are as they should:

[root@camel-vdsc yum.repos.d]# iscsiadm -m session         
tcp: [25] 10.35.160.104:3260,1 iqn.1992-04.com.emc:cx.ckm00121000438.a6
tcp: [26] 10.35.160.105:3260,2 iqn.1992-04.com.emc:cx.ckm00121000438.a7
tcp: [27] 10.35.160.106:3260,3 iqn.1992-04.com.emc:cx.ckm00121000438.b6
tcp: [28] 10.35.160.107:3260,4 iqn.1992-04.com.emc:cx.ckm00121000438.b7 (see devices file)

During maintenance:

[root@camel-vdsc yum.repos.d]# iscsiadm -m session
iscsiadm: No active sessions. (see devices file)

After detach:
[root@camel-vdsc yum.repos.d]# iscsiadm -m session
tcp: [30] 10.35.160.107:3260,4 iqn.1992-04.com.emc:cx.ckm00121000438.b7
tcp: [32] 10.35.160.105:3260,2 iqn.1992-04.com.emc:cx.ckm00121000438.a7
tcp: [34] 10.35.160.106:3260,3 iqn.1992-04.com.emc:cx.ckm00121000438.b6
(see device file)

The ui reports host as being connected to all iqn's, now, when attempting this flow again, the result we get is a constant iqn status which doesn't change(even when not having any domains up)

Version-Release number of selected component (if applicable):
vt10

How reproducible:
100%

Steps to Reproduce:
1.create iSCSi domain
2.detach it


Actual results:
upon detach, host is connected to ( $NUM_OF_SESSIONS -1 ) iqn's, iqn sessions number don't change after this operation

Expected results:
detaching an iSCSi domain shouldn't prompt any iqn login, in our case I expect to see no sessions after detach domain.
