mm/damon/sysfs: handle clear_schemes_tried_regions from DAMON sysfs context
DAMON sysfs interface handles clear_schemes_tried_regions request from the
DAMON callback context (damon_sysfs_cmd_request_callback()), which is
designed to be used for safe access to the related DAMON context internal
data. But no DAMON context internal data is accessed for the work.
Directly handle it from DAMON sysfs interface context, namely
damon_sysfs_handle_cmd().
