    crypt: don't share DH secret between main and crypto helper threads
    Instead transfer it back and forth between the state and helper
    objects so that, at any point, there is only one owner.  Blame IKEv1
    for this added complexity in the comments; pure IKEv2 can simply send
    and forget.
    Fixes a use-after-free where the main thread deletes the DH secret
    while the crypto helper is still trying to to use it.
    Does not fix a leak of the DH secret where the crypto helper either
    gets cancelled or finds its state was deleted.
