oom_kill: change oom_kill.c to use for_each_thread()
commit 1da4db0cd5c8a31d4468ec906b413e75e604b465 upstream.
Change oom_kill.c to use for_each_thread() rather than the racy
while_each_thread() which can loop forever if we race with exit.
Note also that most users were buggy even if while_each_thread() was
fine, the task can exit even _before_ rcu_read_lock().
Fortunately the new for_each_thread() only requires the stable
task_struct, so this change fixes both problems.
