media: i2c: imx319: Rectify runtime PM handling probe and remove

Idle the device only after the async sub-device has been successfully
registered. In error handling, set the device's runtime PM status to
suspended only if it has been set to active previously in probe.

Also set the device's runtime PM status to suspended in remove only if it
wasn't so already.
