media: v4l: Reset subdev v4l2_dev field to NULL if registration fails
commit 317efce991620adc589b3005b9baed433dcb2a56 upstream.
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.
