cephfs: set Pool parameter to empty for Snapshot-backed volumes

Browse Source 
Set VolumeOptions.Pool parameter to empty for Snapshot-backed volumes.
This Pool parameter is optional and  only used as 'pool-layout' parameter
during subvolume and subvolume clone create request in cephcsi
and not used for Snapshot-backed volume at all.
It is not saved anywhere for use in subsequent operations after create too.
Therefore, We can set it to empty and not error out.
