After r292066, vdev_geom verifies both the vdev and pool guids of device labels during open. However, spare and l2arc devices don't have pool guids, so opening them by guid will fail (opening by path, when the pathname is known, still succeeds). This change allows a vdev to be opened by guid if the label contains no pool_guid, which is the case for inactive spares and l2arc devices.
