The latter is redundant as the underlying implementation should be able to cope with short input so we should only check the assoclen here. Also this check should be moved to the sendmsg side as that'll make it more obvious as to what went wrong. PS we should add a length check for missing/partial auth tags to crypto_aead_decrypt. We can then remove such checks from individual implementations.
