Bug 8953 - IllegalArgumentException: vrfEntry is missing mandatory
descendant origin

The PNF deletion use cases were missing a few fixes in VPN and FIB
Engines.
1) Even though FIB was created using the external subnetId as the rd, the
external network id was being used to delete the FIB entries.
2) There was a fix in the PNF FIB add cycle to get vpn operational data
using the external network id instead of external subnet id. This was
missing in the deletion cycle.
