Detached LUKS2 header with auth. encryption does not work. We should add
straightforward error message right in 'luksFormat' and 'open' actions.
(interestingly it fails in different code up to 2.0.6 and post 2.1.0,
but it doesn't work in either release). From my perspective it's a bug
that it fails so late in crypt_format() code.
Right now, I'm not sure if it's only unfinished feature from userspace
perspective or we miss something also in kernel to make it work correctly.
