Public bug reported:
nec plugin deletes and recreate a OFC port unexpectedly when update_port from
dhcp-agent
even though there is no actual changes in OpenFlow port information
(datapath_id and port number).
It is caused by normalization of datapath_id is different between when
plugin.update_port is called and when portinfo upadte is notified from
nec-plugin-agent. As a result, nec-plugin will mis-recognize datapath_id is
changed and recreate a port on OpenFlow controller. This leads to unexpected
temporary outage of a dhcp port.
The same normalization method should be used for both case.
