mac80211/minstrel_ht: increase sampling frequency of some slower rates
If a rate is below the max_tp_rate, sample it frequently if: - it is above max_tp_rate2, or - it is above max_prob_rate and is a candidate for max_prob_rate (has fewer streams than max_tp_rate). This helps the retry chain recover more quickly from bad statistics caused by collisions or interference, and slightly reduces throughput fluctuations with higher rates.
