Summary

We already increment the unicast IPACKETS and OPACKETS counters in the
rx/tx paths, respectively. Multicast packets are counted in the generic
ethernet code. Therefore, we shouldn't increment these counters in
dwc_harvest_stats().

Drop the early return from dwc_rxfinish_one() so that we still count
received packets with e.g. a checksum error.
