ip: The check for 'same packet' must include the FIB index

Type: fix

otherwise if two packets arrive with the same source address but from different VRFs, then they are treated as the same and they use the same LB and thus share the same fate. but the lookup, when done, results in two different LBs, and hence the fate can be different.
