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.
