vbo: return VP_NONE from get_program_mode() if running fixed-func vertex program
If we're running a vertex program to emulated fixed-function, we still need
to treat vertex arrays/attributes as if we're in fixed-function mode.
This should probably be back-ported to Mesa 7.5 after a bit more testing.
