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.
