[BUG] volume is stuck in attaching/detaching loop with error Failed to init frontend: device... #4959

Volume stuck in attaching/detaching loop with the error:

2022-11-24T11:26:30.985743332Z tgtd: target_mgmt(147) Failed to unbind by address: ALL
Failed to init frontend: device pvc-3b45d723-d8fa-4c75-b334-0508faa92ea0: fail to delete target iqn.2019-10.io.longhorn:pvc-3b45d723-d8fa-4c75-b334-0508faa92ea0

From Longhorn engine, the error tgtd: target_mgmt(147) Failed to unbind by address: ALL comes from this function call

From the tgtadm, it comes from this line of code. Digging deeper we can see that it was probably there is no tgt target with the corresponding target id at here

@innobead and I feel like we shouldn't error out when trying to unbind while tgt target does not exist. However, we will need to investigate more and try to reproduce the issue
