libceph: use con get/put ops from osd_client
There were a few direct calls to ceph_con_{get,put}() instead of the con ops from osd_client.c. This is a bug since those ops aren't defined to be ceph_con_get/put. This breaks refcounting on the ceph_osd structs that contain the ceph_connections, and could lead to all manner of strangeness. The purpose of the ->get and ->put methods in a ceph connection are to allow the connection to indicate it has a reference to something external to the messaging system, *not* to indicate something external has a reference to the connection.
