This works because we mostly just care that the color location isn't
WINED3D_LOCATION_DRAWABLE if there's no attachment. (In particular for
the case where the application is doing depth only rendering.)
Strictly speaking though, it's probably more correct to use the color
location if there's no depth/stencil attachment, to avoid silliness
like the color attachment being in WINED3D_LOCATION_DRAWABLE and the
depth/stencil attachment in WINED3D_LOCATION_TEXTURE_RGB. In fact, now
that the color and depth/stencil locations are separate, you can
probably just pass 0.
