[PATCH v2 3/3] selftests/mm: kmemleak: drop stale min_unref_scans default from comments

[Breno Leitao]

The test writes min_unref_scans explicitly for every case, so its comments
describing 1 as the default are both unnecessary and, since the default is
now conditional, wrong. Refer to the threshold values directly.

No functional change.
