ceph: allow connection to be reopened by fault callback
Fix the messenger to allow a ceph_con_open() during the fault callback. Previously the work wasn't getting queued on the connection because the fault path avoids requeued work (normally spurious). Loop on reopening by checking for the OPENING state bit. This fixes OSD reconnects when a TCP connection drops. Signed-off-by: Sage Weil <sage@newdream.net>
