Public bug reported:

Port status goes BUILD when migrating non-sriov instance in sriov
setting.

Test

1. Deploy Antelope with juju ( upstream also has the same code )
2. Enable SRIOV
3. create a vm without sriov nic. (test)
4. migrate it to another host
- openstack server migrate --live-migration --os-compute-api-version 2.30 --host node-04.maas test
5. check port status
- https://paste.ubuntu.com/p/RKGnP76MvB/

nova-compute has neutron-sriov-nic-agent and neutron-ovn-metadata-agent

So far, I've checked that

ovn_monitor change it to ACTIVE but sriov-nic-agent change it back to
BUILD by calling _get_new_status

./plugins/ml2/drivers/mech_sriov/agent/sriov_nic_agent.py
binding_activate
- get_device_details_from_port_id
- get_device_details
- _get_new_status < this makes status BUILD.

so as running order is not fixed, sometimes it goes ACTIVE, sometimes
BUILD.
