wined3d: CreateDevice should use the root window.

[Jan Zerebecki]

If this patch is rejected from inclusion, please tell me why, as i would have to
ask anyway.

This was already fixed in the old d3d8 code.

From: Jan Zerebecki <jan.wine at zerebecki.de>
Changelog:
wined3d: CreateDevice should use the root window.
Because only the root has __wine_x11_whole_window.
