Bug 8581: DNAT failure with openstack/ocata

Problem Statement:
===================
DNAT traffic is getting failed because of missing DNAT flows in switch
(DPN). This issue was observed in openstack stable/ocata only.

Solution:
==========
Due to invalid check in NeutronPortListener.update(), certain FIP DS entry
where not populated and as a result, required DNAT flows where not installed.
Changes done to create required FIB DS entries properly.
