[Qemu-devel] [PULL 4/7] libqos: fix qvring_init()

[Stefan Hajnoczi <stefanha@redhat.com>]

From: Laurent Vivier <lvivier@redhat.com>

"vq->desc[i].addr" is a 64bit value,
so write it with writeq(), not writew().

struct vring_desc {
    __virtio64 addr;
    __virtio32 len;
    __virtio16 flags;
    __virtio16 next;
};
