When subdev registration fails the subdev v4l2_dev field is left to a non-NULL value. Later calls to v4l2_device_unregister_subdev() will consider the subdev as registered and will module_put() the subdev module without any matching module_get(). Fix this by setting the subdev v4l2_dev field to NULL in v4l2_device_register_subdev() when the function fails.
