virtio: remove set_handler argument from set_host_notifier_internal

Make virtio_device_start_ioeventfd_impl use the same logic as
dataplane to set up the host notifier.  This removes the need
for the set_handler argument in set_host_notifier_internal.

This is a first step towards using virtio_bus_set_host_notifier
as the sole entry point to set up ioeventfds.  At least now
the functions have the same interface, but they still differ
in that virtio_bus_set_host_notifier sets ioeventfd_disabled.
