[PATCH 13/19] mm/damon/core: s/max_nr_accesses/max_merge_score/ in kdamond_fn()

[SJ Park <sj@kernel.org>]

When probe weights are set, DAMON merge logic works with the probe hits
weighted sum.  The core logic is setting the merge threshold based on
the access frequency, though.  Before using probe hits based threshold,
rename the variables to look more general.
