samples/damon/mtier: avoid starting DAMON before initialization

Browse Source 
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.
