Subject: [PATCH 097/270] libceph: use con get/put methods

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

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

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

commit 36eb71aa57e6a33d61fd90a2fd87f00c6844bc86 upstream.

The ceph_con_get/put() helpers manipulate the embedded con ref
count, which isn't used now that ceph_connections are embedded in
other structures.
