mkcephfs: error out if mon data directory is not empty

Browse Source 
The ceph-mon --mkfs function no longer wipes out the directory; it is in
fact mostly a no-op that just verifies the dir exists.

So, ensure that the directory is empty at mkfs time.  This could
alternatively do an 'rm -r' in that directory (that is in fact what
ceph-mon used to do), but this is safer.
