XQuartz: RandR: Fix mode changing for multi-monitor configurations.

Browse Source 
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.
