SeongJae Park 76126332c7 mm/damon/sysfs: avoid empty scheme tried regions for large apply interval

DAMON_SYSFS assumes all schemes will be applied for at least one DAMON
monitoring results snapshot within one aggregation interval, or makes no
sense to wait for it while DAMON is deactivated by the watermarks.  That
for deactivated status still makes sense, but the aggregation interval
based assumption is invalid now because each scheme can has its own apply
interval.  For schemes having larger than the aggregation or watermarks
check interval, DAMOS tried regions update request can be finished without
the update.  Avoid the case by explicitly checking the status of the
schemes tried regions update and watermarks based DAMON deactivation.
