RAID:  Disallow addition of RAID images while array is not in-sync

We cannot add images to a RAID array while it is not in-sync.  The
kernel will simply reject the table, saying:
	'rebuild' specified while array is not in-sync
Now we check to ensure the LV is in-sync before attempting image
additions.
