[PATCH 6.12 32/42] cpuset: Fix missing adaptation for cpuset_is_populated

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Chen Ridong <chenridong@huawei.com>

Commit b1bcaed1e39a ("cpuset: Treat cpusets in attaching as populated")
was backported to the long‑term support (LTS) branches. However, because
commit d5cf4d34a333 ("cgroup/cpuset: Don't track # of local child
partitions") was not backported, a corresponding adaptation to the
backported code is still required.

To ensure correct behavior, replace cgroup_is_populated with
cpuset_is_populated in the partition_is_populated function.
