[mutter/wip/carlosg/x11less-preparations: 4/18] core: Separate checks for pointer barriers availability



commit b8da69cc88f65f3a15b625fc5a1cd455bee84d17

    core: Separate checks for pointer barriers availability
    
    If the check happens on --nested (X11 backend) while there is no X11
    display we would get a crash. Since the barriers are non-effective on
    nested, just take it out into a separate condition.
