pvscan: handle case of scanning PV without metadata last

Handle the case where pvscan --cache -aay (with no dev args)
gets to the final PV, completing the VG, but that final PV does not
have VG metadata.  In this case, we need to use VG metadata from a
previously scanned PV in the same VG, which we saved for this
possibility.  Using this saved metadata, we can find which VG
this PVID belongs to, and then check if that VG is now complete,
and if so add the VG name to the list of complete VGs to be
autoactivated.
