Jeff Layton a090cc6969 ceph: don't leak snap_rwsem in handle_cap_grant 
commit 58dd4385577ed7969b80cdc9e2a31575aba6c712 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.

Fixes: 6f05b30ea063 ("ceph: reset i_requested_max_size if file write is not wanted")
