virtio_ring: virtqueue_add_outbuf / virtqueue_add_inbuf. These are specialized versions of virtqueue_add_buf(), which cover over 80% of cases and are far clearer. In particular, the scatterlists passed to these functions don't have to be clean (ie. we ignore end markers). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
