[PATCH] virtio: remove obsolete virtqueue_get_queue_index()

[PATCH] virtio: remove obsolete virtqueue_get_queue_index()

[Rusty Russell]

You can access it directly now, since 3.8: v3.7-rc1-13-g06ca287
'virtio: move queue_index and num_free fields into core struct
virtqueue.'

(Handing to DaveM for Ack or just take it...)
