virtio-rng: fix boot with virtio-rng device
Commit "virtio-rng: support multiple virtio-rng devices" has broken boot with a virtio-rng device because the 'init' callback of the virtio-rng device was left unitialized to garbage, and got called by the hwrng infrastructure, killing the guest on boot. Signed-off-by: Sasha Levin <sasha.levin@oracle.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Fixes: 08e53fbdb85c0f6f45c0f7c1ea3defc1752a95ce
