cpuset: Fix missing adaptation for cpuset_is_populated
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.
