cgroup: Return -ENODEV consistently for a dead cgroup
cgroup_kn_lock_live() returns NULL when the cgroup behind a kernfs node has
already been removed. Most callers turn that into -ENODEV, but the
cgroup.type, cgroup.max.descendants, cgroup.max.depth, cgroup.pressure,
cgroup.freeze and cgroup.kill writers return -ENOENT. The divergence is
accidental. Return -ENODEV from all of them, matching cgroup.procs and
cgroup.subtree_control.
