libceph: define and use an explicit CONNECTED state
(cherry picked from commit e27947c767f5bed15048f4e4dad3e2eb69133697)
There is no state explicitly defined when a ceph connection is fully
operational. So define one.
It's set when the connection sequence completes successfully, and is
cleared when the connection gets closed.
Be a little more careful when examining the old state when a socket
disconnect event is reported.
