    sna: Hook into crtc_notify rather than ModeSet

    ModeSet is called after updating each CRTC, unlike crtc_notify which is
    called after applying all changes. The last is what we need as if we are
    called too early we detect that the next CRTC doesn't match our
    expectations and so we disable it, right before applying the desired
    mode.

Do you mind repeating your testing and attaching Xorg & dmesg? Thanks.
