media: qcom: camss: cleanup media device allocated resource on error path

A call to media_device_init() requires media_device_cleanup() counterpart
to complete cleanup and release any allocated resources.

This has been done in the driver .remove() right from the beginning, but
error paths on .probe() shall also be fixed.
