VIRTIO_F_ORDER_PLATFORM is needed feature when working with
real HW platforms that are exposing virtio-net devices
via VDPA framework. This feature helps in having more
real ordering requirements between descriptor updates and
notification data updates. Hence enable it if the
device supports the feature.
