There is currently only one place to reference __vring_new_virtqueue()
directly from the outside of virtio core. And here vring_new_virtqueue()
can be used instead.
Subsequent patches will modify __vring_new_virtqueue, so stop it as an
export symbol for now.

Let's remove the duplicated vring_init() here.
With this removed:
