The ioctl arguments are under control of the user and as such we should
resist any temptation to flood the kernel logs with their errors.
Relegate the DRM_ERROR to a DRM_DEBUG so the user has to opt into
hearing of their own mistakes. (One day we will have a small ringbuffer
attached to the task, so that the concerned process can inspect its own
debug info for EINVAL without them being hitting syslog at all.)
