port_update_postcommit doesn't see latest version of object

[Omer Anson]

Dragonflow's ML2 mechanism driver implements port_update_postcommit, and saves the port object (after translation) to its distributed database.

In Dragonflow's tests [1], this object is compared with the object in the Neutron db (specifically the revision_number, which is translated to version on the Dragonflow object)

Currently, this test fails, since the versions are different, even though there were no additional modifications to the port.

I suspect this was added by patch https://review.openstack.org/#/c/475646 , which updates the port's revision number.
