virtio: merge virtio_queue_aio_set_host_notifier_handler with virtio_queue_set_aio

Browse source 
Eliminating the reentrancy is actually a nice thing that we can do
with the API that Michael proposed, so let's make it first class.
This also hides the complex assign/set_handler conventions from
callers of virtio_queue_aio_set_host_notifier_handler, which in
fact was always called with assign=true.
