[PATCH 31/31] media: au0828 change to check media device unregister progress state

[Shuah Khan]

Change au0828_unregister_media_device() to check media
device media device unregister is in progress and avoid
calling media_device_unregister() and other cleanup done
in au0828_unregister_media_device().
