3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Elder <elder@inktank.com>
(cherry picked from commit 3ec50d1868a9e0493046400bb1fdd054c7f64ebd)
A connection state's NEGOTIATING bit gets set while in CONNECTING state after we have successfully exchanged a ceph banner and IP addresses with the connection's peer (the server). But that bit is not cleared again--at least not until another connection attempt is initiated.
Instead, clear it as soon as the connection is fully established. Also, clear it when a socket connection gets prematurely closed in the midst of establishing a ceph connection (in case we had reached the point where it was set).
