Subject: mm/damon/core: invoke kdamond_call() after merging is done if possible
Date: Thu, 6 Mar 2025 09:58:57 -0800

kdamond_call() callers may iterate the regions, so better to call it when
the number of regions is as small as possible.  It is when
kdamond_merge_regions() is finished.  Invoke it on the point.

This change is also aimed to make future changes for carrying online
parameters commit with damon_call() easier.  The commit operation should
be able to make sequence between other aggregation interval based
operations including regioins merging and aggregation reset.  Placing
damon_call() invocation after the regions merging makes the sequence
handling simpler.
