Subject: [PATCH] rbd: initialize snap_rwsem in rbd_add()

New rbd device structures get initialized in rbd_add().  Many of
the fields rely on being initially zero-filled.  However we lockdep
was noticing that the rw_semaphore embedded in the header field
was not getting properly initialized.  Fix that.
