[RFC PATCH 5/9] mm/damon/sysfs-schemes: kobject_del() scheme filter dirs

[SeongJae Park <sj@kernel.org>]

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 filter directories by adding kobject_del()
calls.

Fixes: 472e2b70eda6 ("mm/damon/sysfs-schemes: connect filter directory and filters directory")
