iwlwifi: mvm: rs: reinit rs if no tx for a long time
After being idle for a long time (>5sec) the rs statistics will be stale so we prefer to reset rs and start from legacy rates again. This gives better results when the attenuation increased signficantly (e.g. we got further from the AP) and after a while we start Tx Note that the first Tx after the idle period will still go out in the old modulation and rate but this seemed a simpler approach compared to adding a timer or modifying mac80211 for this. The negative impact is negligble as we'll recover quickly.
