nat: ED: store both thread&session idx in hash
By storing thread and session index in hash table we are able to skip
multiple hash lookups in multi-worker scenario, which were used for
handoff before. Also, by storing sesion index in vnet_buffer2, we can
avoid repeating the lookup after handoff.
Type: improvement
