Failing to unpublish may lead to missing volume target

[tiagolobocastro]

Describe the bug
In a cluster it was observed that the volume target was not coming up.

AttachVolume.Attach failed for volume "pvc-xxxx" : rpc error: code = Internal desc = Volume xxx reports no info about its publishing status

To Reproduce
I think this is as a result of a previous controller unpublish failure (returned to CSI), but eventually it succeeded "out of band", without the csi-controller's intervention.

Expected behavior
A new target should be created!

Additional context
A WA is to force the app pod to move to another node, thus re-triggering the controller publish.
