anv: fix index buffer emission

Browse Source 
In the following case :

  vkCmdBindPipeline(compute_pipeline);
  vkCmdDispatch(...);
  vkCmdBindPipeline(graphics_pipeline);
  vkCmdBindIndexBuffer(buffer)
  vkCmdDraw(...);

We're emitting the 3DSTATE_INDEX_BUFFER instruction while the HW is
still in GPGPU mode, because we're dealing the pipeline selection to
vkCmdDraw().

Found while debugging Age Of Empire 4, HW is hung on
3DSTATE_INDEX_BUFFER instruction.
