Public bug reported:

If deleted service records are present in the database, the Service
minimum version calculation should ignore them, but it does not. One
manifestation of this is the PCI device migration from mitaka/newton
will never complete, emitting an error message like this:

2017-02-27 07:40:19.665 ERROR nova.db.sqlalchemy.api [req-ad21480f-613a-
445b-a913-c54532b64ffa None None] Data migrations for PciDevice are not
safe, likely because not all services that access the DB directly are
updated to the latest version
