This one is wrong, and similar transformations.

As a general comment, not on your patch, this assert doesn't provide
anywhere near the right information. rc here is either -1 or 0, it's the
errno that's interesting (fortunately also printed by the assert), but
it is igt_assert_eq(drmModeModeCursor(drm.fd, params->crtc_id, 0, 0), 0);
that provides the most useful immediate debugging aid.
