    virtio_blk - Clean up detach code, to work better for multiqueue.
    
    * Specifically this uses the fact that vtblk_flags is only ever modified in
      vtblk_attach(), vtblk_detach(), vtblk_suspend(), and vtblk_resume(). So
      we don't need to worry about taking all the serializers when setting the
      DETACH flag.
    
    * Additionally the virtqueue_disable_intr() call from vtblk_stop() was
      completely superfluous, since the virtio_teardown_intr() call earlier
      already guarantees that none of the virtqueue interrupt handlers can be
      active anymore.
