mm/damon/sysfs: remove damon_sysfs_destroy_targets()
The function was introduced for putting pids and deallocating unnecessary
targets. Hence it is called before damon_destroy_ctx(). Now vaddr puts
pid for each target destruction (cleanup_target()). damon_destroy_ctx()
deallocates the targets anyway. So damon_sysfs_destroy_targets() has no
reason to exist. Remove it.
