[PATCH RFC v4 16/16] virtio-net: enable virtio 1.0

virtio-net (non-vhost) now should have everything in place to support
virtio 1.0: let's enable the feature bit for it.

Note that VIRTIO_F_VERSION_1 is technically a transport feature; once
every device is ready for virtio 1.0, we can move setting this
feature bit out of the individual devices.
