[Mesa-dev] [PATCH] mesa: Remove unnecessary FLUSH_VERTICES in bind_buffer_range

[Paul Berry]

It isn't necessary to call FLUSH_VERTICES from bind_buffer_range,
because transform feedback buffers are not allowed to be changed when
transform feedback is active.

Thanks to Marek Olšák for pointing out this bug.
