Subject: mm: revert slight behavior change for swappiness 1-200
Date: Thu, 3 Sep 2026 14:48:52 +0800

Baoquan's review found that we unexpectedly introduced a slight behavior
change for swappiness 1-200. We could now have a case like:

1. First scan -> `scanned != 0`
2. Second scan -> `scanned = 0`
3. Type fallback

Step 3 was impossible before. Let's remove this possibility.
