mac80211/minstrel_ht: fix spacing between sample attempts
A sample attempt should only count in mi->sample_tries if the sample attempt wasn't skipped based on slower rate criteria. This patch increases the sampling frequency for potentially desirable rates and thus enables faster recovery from interference or collisions.
