wined3d: Only translate coordinates for swapchain surfaces in surface_translate_drawable_coords().

This fixes a regression introduced by commit
dbd8c89ea8cd1d887e9999d203da3e79c4ffbd1a. When using ORM_BACKBUFFER,
off-screen surfaces may be loaded into WINED3D_LOCATION_DRAWABLE. They
shouldn't be flipped in that case.
