Brian Foley d78b519f6b virtio_mmio: Don't attempt to create empty virtqueues ... If a virtio device reports a QueueNumMax of 0, vring_new_virtqueue() doesn't check this, and thanks to an unsigned (i < num - 1) loop guard, scribbles over memory when initialising the free list. Avoid by not trying to create zero-descriptor queues, as there's no way to do any I/O with one.
