[Openstack] nova error migrating with floating ips: 'FixedIP' object has no attribute '_sa_instance_state'

Thanks, Roman. That fix did get past the sa_instance_state problem, but I
bumped into something new. It looks like floating_ip_update() doesn't like
the SA fixed ip that's fetched here:
+ updates['fixed_ip'] = db.fixed_ip_get(context, id_)
I'm not sure what "A conflicting state is already present in the identity
map" means. Is there another way to fetch the fixed ip?
