virtio: remove event notifier cleanup call on de-assign
The virtio_bus_set_host_notifier function no longer calls
event_notifier_cleanup when a event notifier is removed.
The commit updates the code to match the new behavior and calls
virtio_bus_cleanup_host_notifier after the notifier was de-assign
and no longer in use.
This change is a preparation to allow executing the
virtio_bus_set_host_notifier function in a memory region
transaction.
