mon/MDSMonitor: respect MDSMAP_DOWN when promoting standbys

Browse Source 
Previously, a standby could become active even if 'cluster_down'
had been run.  This was awkward, because it would get you a
"laggy or crashed" mds for the standby that was actually
up and running, just being ignored because of cluster_down.
