Subject: [PATCH] media: imx355: Avoid calling imx355_power_off twice in error
 path

If v4l2_async_register_subdev_sensor failed, then the sensor had
already been powered down by pm_runtime_idle, but the error path
then also explicitly called imx355_power_off as well. That left
an imbalance in the regulator and clock calls.

Call pm_runtime_idle only after v4l2_async_register_subdev_sensor
succeeds to avoid this.
