Good point. Could we do this as a follow-up patch? Reposting
the whole series would disturb a lot of people. Of course if
other major issues crop up I can fold this into the existing

The function tls_encrypt_done only uses aead_req to get ahold of
the tls_rec object. So we could pass that in instead of aead_req
to simplify the code.
