Don't set stacking order against unvisible windows

[Uwe Bonnes <bon@elektron.ikp.physik.tu-darmstadt.de>]

Changelog:
        dlls/x11drv/window.c: X11DRV_sync_whole_window_position
        Don't specify a stacking order agains unvisible windows

This let the Capital Einkommenssteuer 2003 (Infotax/Steuer02) Installer run
in Desktop mode. Otherwise X throws a bad match error.
