ceph: avoid resending queued message to monitor
The auth_reply handler will (re)send any pending requests. For the
initial mon authenticate phase, that's correct, but when a auth ticket
renewal races with an in-flight request, we may resend a request message
that is already in flight. Avoid this by revoking the message before
sending it.
We should also avoid resending requests at all during ticket renewal; that
will come soon.
