Subject: [PATCH 131/270] libceph: close socket directly from ceph_con_close()

3.5.7u1 -stable review patch.  If anyone has any objections, please let me know.

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

From: Sage Weil <sage@...tank.com>

commit ee76e0736db8455e3b11827d6899bd2a4e1d0584 upstream.

It is simpler to do this immediately, since we already hold the con mutex.
It also avoids the need to deal with a not-quite-CLOSED socket in con_work.
