Subject: selftests/damon/_damon_sysfs: read tried regions directories in order
Date: Mon, 12 May 2025 17:27:14 -0700

Kdamond.update_schemes_tried_regions() reads and stores tried regions
information out of address order.  It makes debugging a test failure
difficult.  Change the behavior to do the reading and writing in the
address order.
