NEC plugin fails to process portinfo message after port delete

[Akihiro Motoki]

portinfo RPC message (port_removed, port_added) in NEC plugin may be sent after the corresponding quantum port is deleted. A portinfo RPC message can contain multiple added/removed portinfo and if an exception occurs the remaining portinfos are not processed.

The failure in port_removed can happen in a usual operationing. The order of quantum port deletion and port_removed message is not ensured, since NEC plugin agent polls OVS ports by polling ovsdb.

The failure in port_added does not happen in usual operation. It may occur in a case where some OVS ports are not removed successfully for some reason and nec-agent is restarted after that.
