Peter Seiderer 5c6dd7bd56 mac80211: minstrel_ht: fix where rate stats are stored (fixes debugfs output)
Using an ath9k card the debugfs output of minstrel_ht looks like the following
(note the zero values for the first four rates sum-of success/attempts):

             best    ____________rate__________    ____statistics___    _____last____    ______sum-of________
mode guard #  rate   [name   idx airtime  max_tp]  [avg(tp) avg(prob)]  [retry|suc|att]  [#success | #attempts]

Debugging showed that the rate statistics for the first four rates where
stored in the MINSTREL_CCK_GROUP instead of the MINSTREL_OFDM_GROUP because
in minstrel_ht_get_stats() the supported check was not honoured as done in
various other places, e.g net/mac80211/rc80211_minstrel_ht_debugfs.c:

 74                 if (!(mi->supported[i] & BIT(j)))
 75                         continue;

With the patch applied the output looks good:

              best    ____________rate__________    ____statistics___    _____last____    ______sum-of________
mode guard #  rate   [name   idx airtime  max_tp]  [avg(tp) avg(prob)]  [retry|suc|att]  [#success | #attempts]
