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.
