[RFC PATCH 05/13] mm/damon/sysfs-schemes: use damon_nr_accesses_mvsum() for damo regions

[SeongJae Park <sj@kernel.org>]

damon_nr_accesses_mvsum() returns a value same to nr_accesses_bp.  Also
the function is more simple and therefore more tolerant to errors.
Execution of the function would be more expensive than the simple read
of the field, but because the function is quite simple, the overhead
should be negligible.  Use it in the DAMON sysfs interface for
scheme-tried regions, instead of the nr_accesses_bp.
