mm/damon/sysfs-schemes: fix wrong DAMOS tried regions update timeout setup
DAMON sysfs interface's update_schemes_tried_regions command has a timeout
of two apply intervals of the DAMOS scheme. Having zero value DAMOS
scheme apply interval means it will use the aggregation interval as the
value. However, the timeout setup logic is mistakenly using the sampling
interval insted of the aggregartion interval for the case. This could
cause earlier-than-expected timeout of the command. Fix it.
