Revert "oom: oom_kill_process: fix the child_points logic"

This reverts the parent commit. I hate doing that, but it's generating
some discussion ("half of it is right"), and since I am planning on
doing the 2.6.38 release later today we can punt it to stable if
required. Let's not rock the boat right now.
