Will return -EINVAL using standard framework api when test stateless
decoder with cmd VIDIOC_(TRY)DECODER_CMD.

Using another return value to adjust v4l2 compliance test for user
driver(GStreamer/Chrome) won't use decode cmd.

Hello Yunfei,

this patch is a fix.. hence, this needs an appropriate Fixes: tag.
Please add one.

Thanks,
Angelo
