d3d8: CreateDevice should use the root of the current window

[Jan Zerebecki]

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

From: Jan Zerebecki <jan.wine at zerebecki.de>
Changelog:
d3d8: CreateDevice should use the root of the current window
because if it's not the root, it doesn't have the property
__wine_x11_whole_window .
Fixes bug #4341 .
