Jeff Layton 58dd438557 ceph: don't leak snap_rwsem in handle_cap_grant
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.

Fixes: 6f05b30ea0 ("ceph: reset i_requested_max_size if file write is not wanted")
