scsi: iscsi: Fail session and connection on transport registration failure
If the transport cannot be registered, the session/connection creation
needs to be failed early to let the initiator know. Otherwise, the system
will have an outstanding connection that cannot be used nor removed by
open-iscsi. The result is similar to the error below, triggered by
injecting a failure in the transport's registration path.
openiscsi reports success:
root@debian-vm:~# iscsiadm -m node -T iqn:lun1 -p 127.0.0.1 -l
Logging in to [iface: default, target: iqn:lun1, portal: 127.0.0.1,3260]
Login to [iface: default, target: iqn:lun1, portal:127.0.0.1,3260] successful.
But cannot remove the session afterwards, since the kernel is in an
inconsistent state.
root@debian-vm:~# iscsiadm -m node -T iqn:lun1 -p 127.0.0.1 -u
iscsiadm: No matching sessions found
