Subject: mm/damon/core-test: fix wrong expectations for 'damon_split_regions_of()'
Kunit test cases for 'damon_split_regions_of()' expects the number of
regions after calling the function will be same to their request
('nr_sub'). However, the requested number is just an upper-limit, because
the function randomly decides the size of each sub-region. This commit
fixes the wrong expectation.
