Subject: [ 116/171] libceph: use con get/put methods

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

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

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

(cherry picked from commit 36eb71aa57e6a33d61fd90a2fd87f00c6844bc86)

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.
