[PATCH RESEND] mm/damon/stat: deduplicate intervals_goal setup in damon_stat_build_ctx()

[SeongJae Park]

From: JaeJoon Jung <rgbi3307@xxxxxxxxx>

The damon_stat_build_ctx() function sets the values of intervals_goal
structure members.  These values are applied to damon_ctx in
damon_set_attrs().  However, It is resetting the values that were already
applied previously to the same values.  I suggest removing this code as it
constitutes duplicate execution.
