virtio: check for vring setup in virtio_queue_update_used_idx
If the vring has not been set up, it is not necessary for vring_used_idx to do anything (as is already the case when the caller is virtio_load). This is harmless for now, but it will be a problem when the MemoryRegionCache has not been set up.
