[PATCH net 2/2] virtio_net: unmap AF_XDP header with tx virtqueue

Message-ID <[email protected]>
virtnet_xsk_pool_enable() maps the shared AF_XDP transmit header with
the send virtqueue, and the disable path unmaps it with the same queue.
Use sq->vq on the setup error path as well so the DMA unmap matches the
mapping side.
