virtio: Introduce virtio_add_queue_aio
Using this function instead of virtio_add_queue marks the vq as aio
based. This differentiation will be useful in later patches.
Distinguish between virtqueue processing in the iohandler context and main loop
AioContext. iohandler context is isolated from AioContexts and therefore does
not run during aio_poll().
