mm/damon/core: skip updating nr_accesses_bp for each aggregation interval

damon_merge_regions_of(), which is called for each aggregation interval,
updates nr_accesses_bp to nr_accesses * 10000.  However, nr_accesses_bp is
updated for each sampling interval via damon_moving_sum() using the
aggregation interval as the moving time window.  And by the definition of
the algorithm, the value becomes same to discrete-window based sum for
each time window-aligned time.  Hence, nr_accesses_bp will be same to
nr_accesses * 10000 for each aggregation interval without explicit update.
Remove the unnecessary update of nr_accesses_bp in
damon_merge_regions_of().
