[ 156/171] libceph: revoke mon_client messages on session restart

[Greg Kroah-Hartman]

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

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

From: Sage Weil <sage@xxxxxxxxxxx>

(cherry picked from commit 4f471e4a9c7db0256834e1b376ea50c82e345c3c)

Revoke all mon_client messages when we shut down the old connection.
This is mostly moot since we are re-using the same ceph_connection,
but it is cleaner.
