Bug fix to remove (rxnfgpc - hw_stats->gprc) which does not account for phy errors. hw_stats->gprc is the Number of good (non-erred) Rx packets (from the network) that pass L2 filtering and has a legal length as defined by LongPacketEnable. While rxnfgpc is the Number of good (non-erred with legal length) Rx packets (from the network) regardless of packet filtering and receive enablement. Thus hw_stats->gprc can be > rxnfgpc and this calculation should be removed from the calculation of ierrors. Validated with testpmd by sending packets to the interface without forwarding enabled - packets should be dropped and the error counters incremented. v2: - specified the commit that this bug fix fixes.
