[RFC PATCH 6/9] mm/damon/sysfs-schemes: kobject_del() scheme quota goal 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 quota goal directories by adding kobject_del()
calls.

Fixes: 7f262da0a30d ("mm/damon/sysfs-schemes: implement files for scheme quota goals setup")
Cc: <stable@vger.kernel.org> # 6.8.x
