cephfs: remove explicit size setting of cloned volume

Browse Source 
CephFS csi driver explictly set the size of the cloned volume
to the size of parent volume as cephfs mgr was lacking this
functionality previously. However it has been addressed in cephfs
so we dont need explicit size setting.

Ref#https://tracker.ceph.com/issues/46163

Supported Ceph releases:

Ceph versions equal or above - v16.0.0, v15.2.9, v14.2.12
