Jeff Layton f546faa216 ceph: don't leak snap_rwsem in handle_cap_grant ...

commit 58dd438557 upstream.

When handle_cap_grant is called on an IMPORT op, then the snap_rwsem is
held and the function is expected to release it before returning. It
currently fails to do that in all cases which could lead to a deadlock.
