Paolo Bonzini ca0176ad83 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.
