mac80211: call rate_control_send_low() internally

Browse source 
There's no rate control algorithm that *doesn't* want to call
it internally, and calling it internally will let us modify
its behaviour in the future.

/**
* rate_control_send_low - helper for drivers for management/no-ack frames
*
* Rate control algorithms that agree to use the lowest rate to
* send management frames and NO_ACK data with the respective hw
* retries should use this in the beginning of their mac80211 get_rate
* callback. If true is returned the rate control can simply return.
* If false is returned we guarantee that sta and sta and priv_sta is
* not null.
*
* Rate control algorithms wishing to do more intelligent selection of
* rate for multicast/broadcast frames may choose to not use this.
*
* @sta: &struct ieee80211_sta pointer to the target destination. Note
* that this may be null.
* @priv_sta: private rate control structure. This may be null.
* @txrc: rate control information we sholud populate for mac80211.
