mdmon: ping will wait for manage_mon to catch up.

When a 'ping' (empty message) is sent to mdmon, we wait for
'monitor' to do a full loop to make sure it has caught up
with anything that needs doing.
This allows synchronisation between mdadm and mdmon.

Maybe monitor should signal managemon rather than managemon polling...
