wifi: mac80211: don't add VHT capa on links without them

Browse Source 
When a link doesn't have VHT capability, before the rework
we'd have set IEEE80211_CONN_DISABLE_VHT, but now with the
linear progression of 'mode', we no longer have that. Add
an explicit check for VHT being supported, so we don't add
a zeroed VHT capabilities element where it shouldn't be.
