Bug Description

When migrate a instance, the method _post_live_migration will update host value of the floating ip associated with the instancd to dist host. see https://github.com/openstack/nova/blob/stable/folsom/nova/compute/manager.py#L2313 . This operation does not consider whether multi_host is false or there is a nova-network runing on the dist host when using nova-network as the network service.

The floating ip host is supposed to be instance['host'] if network['multi_host'], instead of the migration destination host.

This bug is when using nova-network, which is en route to being deprecated, so setting priority Low.
