The drm_mode->dtd conversion used the crtc timings, whereas the dtd->drm_mod did not set these. Use the standard mode information, not the crtc timings, in both cases to make these two functions proper inverses of each another.
Note that this also kills the risk that we handle interlaced timings inconsistently because the drm core uses half-frames for crtc timings, whereas we need full frames. But interlaced support is pretty decently broken anyway for sdvo encoders, so no big deal.
