Log message:
	When down-converting RAID1, don't activate sub-lvs between suspend/resume
	of top-level LV.
	
	We can't activate sub-lv's that are being removed from a RAID1 LV while it
	is suspended.  However, this is what was being used to have them show-up
	so we could remove them.  'sync_local_dev_names' is a sufficient and
	proper replacement and can be done after the top-level LV is resumed.
