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.

Fixes: 7d6fa31a2fd7 ("mm/damon/sysfs-schemes: add timeout for update_schemes_tried_regions")
