mm/damon/core: use damon_nr_accesses_mvsum() for damos region tracing

Browse source

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 region exporting trace points instead
of the nr_accesses_bp.
