Some plugins may set the port status as DOWN when it is created. This was not
updated when the port was actually up. This patch ensures that gateway and
router ports that are created will be set as ACTIVE when they are actually
up and running.
Ports that are attached to additional bridges in the OVS will only update the
port status as ACTIVE. There will be no tags set on the specific ports as this
will break the existing functionality.
