Keiichi Watanabe 4d343bbf55 devices: virtio: Skip setting up unused virtqueues ... While a host virtio device provides |num_queues| virtqueues, a guest virtio driver doesn't necessarily use all of them. For example, the virtio-blk driver uses only |nr_cpu_ids| virtqueues at most [1]. To avoid checking whether each queue is ready in each device implementation, we can filter them before starting device activation.
