Subject: [ 095/171] libceph: rename socket callbacks

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

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

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

(cherry picked from commit 327800bdc2cb9b71f4b458ca07aa9d522668dde0)

Change the names of the three socket callback functions to make it
more obvious they're specifically associated with a connection's
socket (not the ceph connection that uses it).
