cgroup: Return ERR_PTR from cgroup_kn_lock_live()
cgroup_kn_lock_live() returns NULL when the cgroup is dead and the callers
translate that into an errno themselves. Return ERR_PTR(-ENODEV) instead and
have the callers pass the errno through, so that failures other than a dead
cgroup can be reported through the same return value. No functional change.
