samples/damon/mtier: avoid starting DAMON before initialization
[ Upstream commit c62cff40481c037307a13becbda795f7afdcfebd ]
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.
