mm/damon/sysfs: use damos_walk() for update_schemes_tried_{bytes,regions}

Browse source

DAMON sysfs interface uses damon_callback with its own complicated
synchronization facility to handle update_schemes_tried_bytes and
update_schemes_tried_regions commands.  But damos_walk() can support the
use case without the additional synchronizations.  Convert the code to use
damos_walk() instead.
