mac80211: implement ieee80211_tx_rate_update to update rate
Current mac80211 has provision to update tx status through ieee80211_tx_status() and ieee80211_tx_status_ext(). But drivers like ath10k updates the tx status from the skb except txrate, txrate will be updated from a different path, peer stats. Using ieee80211_tx_status_ext() in two different paths (one for the stats, one for the tx rate) would duplicate the stats instead. To avoid this stats duplication, ieee80211_tx_rate_update() is implemented.
