Subject: [PATCH 04/11] Docs/mm/damon/design: explicitly introduce ``nr_accesses``

The design document is explaining about the access tracking mechanism
and the access rate counter (nr_accesses), but not directly mentions the
name.  Add a sentence for making it clear.

 This scheme, however, cannot preserve the quality of the output if the
 assumption is not guaranteed.
