cephfs: remove extra check for restore size

Browse Source 
Looks like cephfs snapshot size is buggy and its
getting removed in ceph fs. we cannot get the size
of the snapshot during CreateVolume call, so we cannot
do any size check at CreateVolume to check if the
restore size is smaller or not.

As we are removing this check it also fixes #3147
but we dont have any validation at CSI level for
smaller restore we need to depend on kubernetes
external-provisioner for it.

fixes: #3147
