sfc: support variable number of MAC stats
Medford2 NICs support more than MC_CMD_MAC_NSTATS stats, and report the new
count in a field of MC_CMD_GET_CAPABILITIES_V4. This also means that the
end generation count moves (it is, as before, the last 64 bits of the DMA
buffer, but that is no longer MC_CMD_MAC_GENERATION_END).
So read num_mac_stats from the GET_CAPABILITIES response, if present;
otherwise assume MC_CMD_MAC_NSTATS; and always use num_mac_stats - 1 rather
than MC_CMD_MAC_GENERATION_END.
