From: Numan Siddique <numans@ovn.org>

If there is an OVS interface present with the external_ids:iface-id set
to a localport port binding, we create a 'struct local_binding' for this
OVS interface but we do not associate the binding_lport to this
local_binding.  This patch now associates the binding_lport now.
Future patch will make use of this information in handling the
runtime data changes in the pflow engine node.
