media: dmxdev: fix error code for invalid ioctls
Returning -EINVAL when an ioctl is not implemented is a very bad idea, as it is hard to distinguish from other error contitions that an ioctl could lead. Replace it by its right error code: -ENOTTY. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
