drm: replace drawable ioctl by noops
The information supplied by userspace through these ioctls is only accessible by dev->drw_idr. But there's no in-tree user of that. Also userspace does not really care about return values of these ioctls, either. Only hw/xfree86/dri/dri.c from the xserver actually checks the return from adddraw and keeps on trying to create a kernel drawable every time somebody creates a dri drawable. But since that's now a noop, who cares. Therefore it's safe to replace these three ioctls with noops and rip out the implementation.
