drm: remove the dma_ioctl special-case
We might as well have a real ioctl function which checks for the callbacks. This seems to be a remnant from back in the days when each drm driver had their own complete ioctl table, with no shared core drm table at all. To make really sure no mis-guided user in a kms driver pops up again explicitly check for that in the new ioctl implementation. v2: Drop the unused variable I've accidentally left in the code, spotted by David Herrmann.
