This just fixes the regression whereby we couldn't switch between the legacy
fullscreen mode and rootless on multi-monitor configurations. This was
happening because ref wasn't being set in these cases (since we don't ever
actually change CG modes), so we failed a CFEqual. Setting the references
fixes this regression and places us one step closer to more mode RandR
mode switching in multi-monitor configurations.
