trivial, update the comment in kthread_stop()
"kthreads: rework kthread_stop()" commit 63706172f332fd3f6e7458ebfb35fa6de9c21dc5 removed the limitation, but forgot to update the comment. Since that commit it is OK to use kthread_stop() even if kthread can exit itself. Signed-off-by: Oleg Nesterov <oleg@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
