DAMON sysfs interface exposes access rate of each region via DAMOS tried
regions directory.  For this, the nr_accesses field of the region is
used.  DAMOS was actually using nr_accesses in the past, but it uses
nr_accesses_bp now.  Use the value that it is really using as the
source.

Note that this doesn't expose nr_accesses_bp as is (in basis point), but
after converting it to the natural number by dividing the value by
10,000.  Hence there is no behavioral change from users' perspective.
