kernel - Fix kernel crash in sysctl path
* Fix a kernel crash which can occur in a particular sysctl due to some
processes not having a p_textnch path. The sysctl code was assuming that
p->p_textnch would always be valid. procfs already has the added check.
* Fix a race against exit, requiring the proc->p_token to be held.
