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.
