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).
