net: systemport: Fix software statistics for SYSTEMPORT Lite

With SYSTEMPORT Lite we have holes in our statistics layout that make us skip over the hardware MIB counters, bcm_sysport_get_stats() was not taking that into account resulting in reporting 0 for all SW-maintained statistics, fix this by skipping accordingly.
