[PATCH 2/3] Docs/vm/damon/design: Update DAMON-Idle Page Tracking interference handling

[SeongJae Park <sj@kernel.org>]

In DAMON's early development stage before it be merged in the mainline,
it was first designed to work exclusively with Idle page tracking to
avoid any interference between each other.  Later, but still before
be merged in the mainline, because Idle page tracking is fully under the
control of sysadmins, we made the resolving of conflict as the
responsibility of sysadmins.  The document is not updated for the
change, though.  This commit updates the document for that.
