[RFC PATCH 4/9] mm/damon/core: use damos_quota_is_set() in damos_adjust_quota()

Also in: damon, lkml
Subsystem: damon, memory management, the rest · Maintainers: SJ Park, Andrew Morton, Linus Torvalds

damos_adjust_quota() is manually checking if the user set the DAMOS
quota.  There is a dedicated helper, damos_quota_is_set(), for the
purpose.  Use the helper.
