If skcipher registration fails, the function unwinds\nthe earlier AEAD registration with crypto_engine_unregister_aeads(), but it\npasses ARRAY_SIZE(algs), which is the skcipher table size.\n\nUse ARRAY_SIZE(algs_aead) for the AEAD unwind path so the unregister helper\niterates over the same table that was registered.  Also clarify the nearby\ncomment: the crypto registration helpers clean up algorithms registered\nwithin the same call, while this function must still unwind earlier\nsuccessful registration steps."
