oom: dump_tasks use find_lock_task_mm too fix
When find_lock_task_mm() returns a thread other than p in dump_tasks(), its name should be displayed instead. This is the thread that will be targeted by the oom killer, not its mm-less parent. This also allows us to safely dereference task->comm without needing get_task_comm(). While we're here, remove the cast on task_cpu(task) as Andrew suggested.
