DMA address will be saved as sg->dma_address, then
virtqueue_add_vring_packed() will use it directly.
If it is a premapped scene, the transmitted sgs should have saved DMA
address in dma_address, and in virtio core, we need to pass
virtqueue...

[PATCH vhost v1 00/12] virtio core prepares for AF_XDP
