    window/wayland: Don't try to resize window on tear down
    
    When terminating mutter running as a display server, don't try to resize
    maximized windows when unmanaging, as at this point, they will have no
    MetaWaylandSurface. Originally this was done instead of setting the
    net_wm_state to not mess with future window managers, but when we're a
    Wayland compositor, this does not matter.
