    sna: Avoid confusing failure to flip and flipping zero CRTC

    During the present unflip path we blindly try to restore the original
    mode after a flip failure. However, it confuses flipping zero CRTC with
    a genuine failure. This has the result of undoing a DPMS change (e.g.
    xset dpms force dpms) under a DRI3 compositor.
