hw/s390x: Attach default virtio-net devices to the /machine/virtual-css-bridge

The initial virtio-net-ccw devices currently do not have a proper parent
in the QOM tree, so they show up under /machine/unattached - which is
somewhat ugly. Let's attach them to /machine/virtual-css-bridge/virtual-css
instead.
