[PATCH] media: s5p-mfc fix video device release double release in probe error path

Fix Decoder and encoder video device double release in probe error path.
video_device_release(dev->vfd_dec) get called twice if decoder register
fails. Also, video_device_release(dev->vfd_enc) get called twice if encoder
register fails.
