Btw, this probably should just be removed in favour of using the nl80211
based APIs for hostapd ...

But I think as a quick bugfix goes this is fine, but it'd be better to
remove this and either allow hostapd to create the interface with the
proper ieee80211_ptr, or to just use the nl80211-based TX/RX.
