Amos Kong 08e53fbdb8 virtio-rng: support multiple virtio-rng devices 
Current hwrng core supports to register multiple hwrng devices,
and there is only one device really works in the same time.
QEMU alsu supports to have multiple virtio-rng backends.

This patch changes virtio-rng driver to support multiple
virtio-rng devices.
