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.
