      Description of problem:

      For our "default" settings of samba server and StorageClass from https://github.com/openshift/csi-operator/blob/master/test/e2e/samba/samba-server.yaml it's enough for end-user to execute `mkdir dir; chmod a-w dir` inside the volume and SMB CSI Driver will fail to cleanup volume:

      $ kubectl describe pv pvc-793ed532-1297-4a12-845f-23b804a4b304
...
