cleanup: remove unused 'pv_by_path' fn

The pv_by_path might be also dangerous to use as it does not
count with any other metadata areas but the ones found on the PV
itself. If metadata was not found on the PV referenced by the path,
it returned no PV though it might have been referenced by metadata
elsewhere (on other PVs...).
