mm/damon/sysfs-schemes: set probe hits as pseudo moving sums

Browse Source 
DAMON sysfs interface exposes damon_region->probe_hits via probe hit
files.  Because the counters are completed only at the end of the
aggregation interval, users can show incomplete values if they requested
the file content update (update_schemes_tried_regions command) in the
middle of an aggregation interval.  Set the value as the pseudo moving sum
value of the counter, similar to that for nr_accesses.
