[media] media: au0828 fix to clear enable/disable/change source handlers
Fix to clear enable/disable/change source handlers in the media device
when media device is unregistered in au0828_unregister_media_device().
When au0828 module is removed, snd-usb-audio shouldn't call the handlers.
Clearing will ensure snd-usb-audio won't call them once au0828 is removed.
