do not raise exception on ip address recycle operation

Currenty a exception will raise on ip address recycle operation if the ip
address doesn't belong to any allocation pool which will make user unable
to update port, even worse it will make user unable to create new port.
So do not raise exception if the ip address to be recycled doesn't belong
to any allocation, just delete it from the ip allocation table.

Ensure that L3 managed port have status ACTIVE

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.
