Installing VenHw() device paths with this GUID, for the virtio-mmio transports that we detect, enables other modules to recognize those VenHw() nodes. (Note that the actual value doesn't change.) In addition, to avoid reusing GUIDs in unrelated contexts, detach the driver's FILE_GUID from its previous value.
