Cornelia Huck 0830c96d70 virtio: revert host notifiers to old semantics
The host notifier rework tried both to unify host notifiers across
transports and plug a possible hole during host notifier
re-assignment. Unfortunately, this meant a change in semantics that
breaks vhost and iSCSI+dataplane.

As the minimal fix, keep the common host notifier code but revert
to the old semantics so that we have time to figure out the proper
fix.
