DGA bugfix

[Ove Kaaven]

After the ddraw HAL stuff was committed to Wine, one Wine user on #WineHQ
did indeed find a problem ("err:ddraw:unexpected error creating
DirectDrawSurface DIB section" when running in DGA mode), here's an
(extended) one-liner to fix it...

Log:
Ove Kaaven <ovek at transgaming.com>
Fix DGA so it works properly again.
