Parse a new stations HT IE.
ieee80211_ibss_add_sta is called with a new argument, ht capabilities of that
new station.
Luckily there was that function ieee80211_ht_cap_ie_to_sta_ht_cap that is
called. This inserts these HT capabilities into the sta_info struct that is eg
used by the rate algorithm.
As mentioned before, this parameter will be NULL when called from rx.c (main
receive path).
