[gnome-shell/wip/wayland: 370/376] Don't ignore crossing event

    Don't ignore crossing event
    
    We were sometimes ignoring crossing events to avoid unfocusing
    the tray after the user interacted with a legacy icon.
    This can't happen any more, as the tray is modal and all events
    are synthetized, so remove this code, which crashes the shell
    under wayland.
