[132/141] libceph: clear messenger auth_retry flag when we authenticate

[Steven Rostedt]

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

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

From: Sage Weil <sage@xxxxxxxxxxx>

[ Upstream commit 20e55c4cc758e4dccdfd92ae8e9588dd624b2cd7 ]

We maintain a counter of failed auth attempts to allow us to retry once
before failing.  However, if the second attempt succeeds, the flag isn't
cleared, which makes us think auth failed again later when the connection
resets for other reasons (like a socket error).

This is one part of the sorry sequence of events in bug
