kernel - Fix nstopped SMP race during core dump * During a process core dump, p->p_nstopped can be adjusted without holding p->p_token, resulting in a SMP race which can cause p_nstopped to become permanently desynchronized and deadlock the process. * Be robust in a p_nstopped handling case in kern_exit, just in case.
