net/virtio-user: fix feature setting with vhost-net backend

When the backend is vhost-net, virtio-user must work in client mode and
needs to request features from the backend in virtio_user_dev_init().
But currently, virtio-user is assigned to default features in this case.

This patch is to fix this inappropriate feature setting.
