We might get modes in XRROutputInfos that aren't in the XRRScreenResources we get earlier. This always seems to be transient, i.e. when it happens, the X server will usually send us a follow up RRScreenChangeNotify where we then get a "stable" view of the world again. In any case, when these glitches happen, we end up with NULL pointers in the MetaOutput->modes array which makes us crash later on. This patch ensures that doesn't happen. https://bugzilla.gnome.org/show_bug.cgi?id=756660
