mac80211: stop toggling IEEE80211_HT_CAP_SUP_WIDTH_20_40
For VHT, many more bandwidth changes are possible. As a first step, stop toggling the IEEE80211_HT_CAP_SUP_WIDTH_20_40 flag in the HT capabilities and instead introduce a bandwidth field indicating the currently usable bandwidth to transmit to the station. Of course, make all drivers use it. To achieve this, make ieee80211_ht_cap_ie_to_sta_ht_cap() get the station as an argument, rather than the new capabilities, so it can set up the new bandwidth field. If the station is a VHT station and VHT bandwidth is in use, also set the bandwidth accordingly. Doing this allows us to get rid of the supports_40mhz flag as the HT capabilities now reflect the true capability instead of the current setting. While at it, also fix ieee80211_ht_cap_ie_to_sta_ht_cap() to not ignore HT cap overrides when MCS TX isn't supported (not that it really happens...)
