KUnit's try-catch infrastructure now uses vfork_done, which is always
set to a valid completion when a kthread is created, but which is set to
NULL once the thread terminates. This creates a race condition, where
the kthread exits before we can wait on it.
Keep a copy of vfork_done, which is taken before we wake_up_process()
and so valid, and wait on that instead.
