clone creation is failing on CentOS when fstype is xfs about zfs-localpv HOT 2 CLOSED

This issue is specific to xfs only, when we create a clone volume and system is taking time in creating the device.

When we create a clone volume from a xfs filesystem, ZFS-LocalPV will go ahead and generate a new UUID for the clone volumes as we need a new UUID to mount the new clone filesystem. To generate a new UUID for the clone volume, ZFS-LocalPV first replays the xfs log by mounting the device to a tmp localtion.

Here, what is happening is since device creation is slow, so we went ahead and created the tmp location to mount the clone volume but since device has not created yet, the mount failed. In the next try since the tmp location is present, it will keep failing there only at every reconciliation time.

Below log shows the mount failure because the device is not present :

time="2020-07-15T10:02:25Z" level=info msg="created clone zfs-test-pool/pvc-cc253e5f-dd7c-4bd8-abc7-26ff73848323"

In retry it is failing to create the tmp directory
