[gnome-desktop/randr-hotplug: 6/9] Don't force a reprobe of the RANDR outputs on every RANDR event

[Federico Mena Quintero <federico src gnome org>]

    Don't force a reprobe of the RANDR outputs on every RANDR event
    
    The X server sent us a RANDR event, in fact, because it knows the latest
    state of the outputs and it knows that something changed.
