Subject: [PATCH] mac80211: pass station to ieee80211_vht_cap_ie_to_sta_vht_cap

From: Johannes Berg <[email protected]>

Like with HT, make things a bit simpler in future patches by
passing the station to ieee80211_vht_cap_ie_to_sta_vht_cap()
instead of the vht_cap pointer. Also disable VHT here if HT
isn't supported.
