The idea was to keep GetTexture() working as well, but that's not going to work
anyway because of the AddRef() in there, so NULL is probably the right thing to
return. It's a bit curious that it would work before
83761d20a8654a616b557ecdb2869436beae7f95 though, since it would pass the same
uninitialized memory to wined3d_device_set_texture() in that case.
