wined3d: Don't use filtering on textures that need complex fixups in swapchain_blit().

For example, interpolating palette indices doesn't have the desired result.
Should we really want filtering for these cases we could implement it inside
the relevant shaders, after the fixup, but I doubt it's worth the effort.
