Fix FC WaitForAttach not mounting a volume

Browse Source 
WaitForAttach failed consistently with this error:

Heuristic determination of mount point failed:stat
/var/lib/kubelet/plugins/kubernetes.io/fc/<wwn>-lun-0:
no such file or directory

We should create dir first to avoid the error.

Fixes: #52674
