Subject: [PATCH] [media] cx231xx: fix compilation when !CONFIG_MEDIA_CONTROLLER

Commit 1590ad7b5271 ("[media] media-device: split media initialization
and registration") split the media dev initialization and registration
but introduced a build error since media_device_register() was called
unconditionally even when the MEDIA_CONTROLLER config was not enabled:

   drivers/media/usb/cx231xx/cx231xx-cards.c: In function 'cx231xx_usb_probe':
   drivers/media/usb/cx231xx/cx231xx-cards.c:1741:36: error: 'struct cx231xx' has no member named 'media_dev'
     retval = media_device_register(dev->media_dev);

Fixes: 1590ad7b5271 ("[media] media-device: split media initialization and registration")
