Fixes: f6bf669b990004dc69231476d9fcf0b80574e568. 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.
