exit: Stop poorly open coding do_task_dead in make_task_dead
When the kernel detects it is oops or otherwise force killing a task while it exits the code poorly attempts to permanently stop the task from scheduling. I say poorly because it is possible for a task in TASK_UINTERRUPTIBLE to be woken up. As it makes no sense for the task to continue call do_task_dead instead which actually does the work and permanently removes the task from the scheduler. Guaranteeing the task will never be woken up again. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>
