Commit 1f391df44607 ("media: v4l2-async: Use endpoints in __v4l2_async_nf_add_fwnode_remote()") changed the data that is stored in the v4l2_async_subdev internals from the fwnode pointer to the parent device to the fwnode pointer to the matched endpoint. This broke the sensor matching code, which relied on the particular fwnode data in the v4l2_async_subdev internals. Fix this by simply matching the v4l2_async_subdev pointer, which is already available there.
