Subject: [PATCH] mac80211: minstrel_ht: fix MCS_GROUP_RATES usage
Commit 5935839ad735 ("mac80211: improve minstrel_ht rate sorting by
throughput & probability") replaced the constant 8 with MCS_GROUP_RATES
when getting the number of streams of an HT MCS. See commit 7a5e3fa2c81c
("mac80211: minstrel_ht: replace some occurences of MCS_GROUP_RATES").
Fixes: 5935839ad735 ("mac80211: improve minstrel_ht rate sorting by throughput & probability")
