vio9p: avoid null pointer dereference on attach.
Pass "vqs" argument to virtio_child_attach_start(). The virtio API is
not quite clear to me here - there's also a separate setter
virtio_child_attach_set_vqs that performs some additional actions.
Queue setup for Virtio 1.0 accesses virtio_softc::sc_vqs and we didn't
set it. QEMU exposes only the old virtio interface, so it doesn't
trigger the problem.
