[RFC PATCH v1.1 07/11] mm/damon/sysfs-schemes: kobject_del() scheme action destination dirs

[SeongJae Park]

On CONFIG_DEBUG_KOBJECT_RELEASE enabled kernel, lack of kobject_del()
could cause directories creation failures due to the name conflicts. Fix
those issues for scheme action destination directories by adding
kobject_del() calls.

Fixes: 2cd0bf85a203 ("mm/damon/sysfs-schemes: implement DAMOS action destinations directory")
