Subject: [PATCH 60/93] libceph: register request before unregister linger

3.5.7.15 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Elder <elder@...tank.com>

commit c89ce05e0c5a01a256100ac6a6019f276bdd1ca6 upstream.

In kick_requests(), we need to register the request before we
unregister the linger request.  Otherwise the unregister will
reset the request's osd pointer to NULL.
