Subject: samples/damon/mtier: stop all contexts with single damon_stop() call
Date: Mon, 6 Jul 2026 07:06:23 -0700

damon_stop() was theoretically able to return failure while keeping the second context for mtier running. mtier stops its contexts one by one with two damon_stop() call for the reason. damon_stop() is refactored to always successfully stop all requested DAMON contexts. The two calls are unnecessary. Use only single damon_stop() call for all contexts.
