snapshot: Fix snapshot clone postvalidate

    BackPort Of http://review.gluster.org/#/c/12364/

In glusterd_snapshot_clone_postvalidate(), we were deleting
snap object and snap vol, by looking up snapname. Hence, it
was deleting the orignal snapshot from which the clone was
being created

Instead it should fetch the clonename, the respective
clone vol, and its corresponding snap object, and delete them.

Also glusterd_snap_remove(), needs to differentiate a clone
snap object from a snaphsot snap object, as in case of a clone
snap object, we don't have any persisted data in
/var/run/gluster/snaps/ and hence is shouldn't try to delete
anything there.
