BUG9094 Bind to last SF interface if origin node

If the last SF is in one of the possible origin nodes for the
classified traffic, bind the classifier on it's port. This is to be
to handle the possible scenario where origin, last SF and destination
of traffic are on the same node. On this scenario, SFC on last hop will
not de-encapsulate the traffic, instead it will be handed off to the
dispatcher table for the egress classifier function to handle it. To be
able to do this, it needs to be bound to the last SF port.
