Log message:
	Fix bug 733400 - Mirror down conversion when specifying the secondary leg is broke
	
	The operation of deactivating the residual error target LV after removing a
	mirror layer can cause a "device in-use" conflict with udev.  Giving udev a
	poke before calling deactivate_lv eliminates the conflict.  The stick used
	to poke udev is 'sync_local_dev_names'.
