Subject: samples/damon/mtier: avoid starting DAMON before initialization
Date: Mon, 8 Sep 2025 19:22:38 -0700
Commit 964314344eab ("samples/damon/mtier: support boot time enable
setup") is somehow incompletely applying the origin patch [1]. It is
missing the part that avoids starting DAMON before module initialization.
Probably a mistake during a merge has happened. Fix it by applying the
missed part again.
