From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

To simplify the probe error path, enable runtime PM after the
v4l2_async_register_subdev() call.

This change ensures that runtime PM is only enabled once the subdevice
registration is successful, avoiding unnecessary cleanup in the error
path.
