Subject: [PATCH 44/78] libceph: initialize mon_client con only once

commit 735a72ef952d42a256f79ae3e6dc1c17a45c041b upstream.

Do not re-initialize the con on every connection attempt.  When we
ceph_con_close, there may still be work queued on the socket (e.g., to
close it), and re-initializing will clobber the work_struct state.
