The commit 1f1562fcd04a ("cgroup/cpuset: Don't let child cpusets restrict parent in default hierarchy") inteded to relax the check only on the default hierarchy (or v2 mode) but it dropped the check in v1 too.

This patch returns and separates the legacy-only validations so that they can be considered only in the v1 mode, which should enforce the old constraints for the sake of compatibility.
