Currently in intel_hpd_irq_storm_detect() when we detect that the last recorded hotplug wasn't within the period defined by HPD_STORM_DETECT_DELAY, we make the mistake of resetting the HPD count to 0 without incrementing it. This results in us only enabling storm detection when we go +2 above the threshold, e.g. an HPD threshold of 5 would not trigger a storm until we reach a total of 7 hotplugs. So: rework the code a bit so we reset the HPD count when HPD_STORM_DETECT_DELAY has passed, then increment the count afterwards. Also, clean things up a bit to make it easier to undertand.
