libceph: fix fault locking; close socket on lossy fault
(cherry picked from commit 3b5ede07b55b52c3be27749d183d87257d032065)
If we fault on a lossy connection, we should still close the socket
immediately, and do so under the con mutex.
We should also take the con mutex before printing out the state bits in
the debug output.
