The module ownership refcounting was done in media_entity_get/put, but that was very confusing and it did not work either in case an application had a v4l-subdevX device open and the module was unbound. When the v4l-subdevX device was closed the media_entity_put was never called and the module refcount was left one too high, making it impossible to unload it. Since v4l2-subdev.c was the only place where media_entity_get/put was called, just move the functionality to v4l2-subdev.c and drop those confusing entity functions. Store the module in subdev_fh so module_put no longer depends on the media_entity struct.
