xwayland: Only ignore manual redirection by clients for surface window 

If the manual redirection was done by xwl_present_maybe_redirect_window,
we are in control.

This allows xwl_present_maybe_redirect_window to work as intended again.
Previously, xwl_window_update_surface_window would ignore the window
redirected by xwl_present_maybe_redirect_window, which would result in
xwl_present_maybe_redirect_window undoing the redirection and bailing.
