mac80211: add ieee80211_tx_prepare_skb() helper function
This can be used by a driver to prepare skbs for transmission, which were obtained via functions such as ieee80211_probereq_get or ieee80211_nullfunc_get. This is useful for drivers that want to send those frames directly, but need rate control information to be prepared first.
