sfc: Reset derived rx_bad_bytes statistic when EF10 MC is rebooted
If the MC reboots then the stats it reports to us will have been reset. We need to reset ours to get efx_update_diff_stat() working properly. (This is a re-run of commit 876be083b669 'sfc: Reset driver's MAC stats after MC reboot seen'.) Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
