wouldn't the underlined attribute ensure the required alignment?

Yes. Sorry, I overlooked it.

I would remove unneeded CRYPTO_MINALIGN and get the alignment from the
target structure:
        char aead_req_data[sizeof(struct aead_request) +
                           crypto_aead_reqsize(tfm)]
                __attribute__((__aligned__(__alignof__(struct aead_request))));
