net: enetc: fix aggregate RMON counters not showing the ranges

When running "ethtool -S eno0 --groups rmon" without an explicit "--src
emac|pmac" argument, the kernel will not report
rx-rmon-etherStatsPkts64to64Octets, rx-rmon-etherStatsPkts65to127Octets,
etc. This is because on ETHTOOL_MAC_STATS_SRC_AGGREGATE, we do not
populate the "ranges" argument.

ocelot_port_get_rmon_stats() does things differently and things work
there. I had forgotten to make sure that the code is structured the same
way in both drivers, so do that now.
