samples/damon/prcl: avoid starting DAMON before initialization
Commit 2780505ec2b4 ("samples/damon/prcl: fix boot time enable crash") 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.
