iowatcher: Fix filtering of outliers from below
There are lots of trace actions which do not carry a sector with them (e.g.
plug, unplug, ...). Thus sector is 0 for them and that results in trimming
of outliers from below never working. Fix the problem by accounting only
Queue events in the outlier statistics.
