[RFC PATCH 08/11] samples/damon/mtier: stop all contexts with single damon_stop() call

[SJ Park <sj@kernel.org>]

damon_stop() was theoretically able to return failure while keeping the
second context for mtier running.  mtier stops its contexts one by one
with two damon_stop() call for the reason.  damon_stop() is refactored
to always successfully stop all requested DAMON contexts.  The two calls
are unnecessary.  Use only single damon_stop() call for all contexts.
