Carlos Garnacho 1cdb6ada4e gdk/wayland: Check the GdkSurface wl_surface before using it for activation
Double check the GdkSurface has a wl_surface before using it as the activation
token source, since we cannot use NULL surfaces here.

Fixes: https://gitlab.gnome.org/GNOME/gnome-control-center/-/issues/1862
