lvmdbusd: Fix model inconsistency when LV loses interface

Browse Source 
When a LV loses an interface it ends up getting removed and recreated.
This happens after the VGs have been processed and updated.  Thus when
this happens we need to re-check the VGs.

# VGs, thus this should be more efficient. This happens when a LV interface
# changes causing the dbus object representing it to be removed and
