Subject: [ 128/171] libceph: clear CONNECTING in ceph_con_close()

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

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

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

(cherry picked from commit bb9e6bba5d8b85b631390f8dbe8a24ae1ff5b48a)

A connection that is closed will no longer be connecting.  So
clear the CONNECTING state bit in ceph_con_close().  Similarly,
if the socket has been closed we no longer are in connecting
state (a new connect sequence will need to be initiated).
