Subject: [ 151/171] libceph: drop unnecessary CLOSED check in socket state change callback

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

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

(cherry picked from commit d7353dd5aaf22ed611fbcd0d4a4a12fb30659290)


If we are CLOSED, the socket is closed and we won't get these.
