Bugfix
* Failures of alternative implementations of AES or DES single-block
functions enabled with MBEDTLS_AES_ENCRYPT_ALT, MBEDTLS_AES_DECRYPT_ALT,
MBEDTLS_DES_CRYPT_ECB_ALT or MBEDTLS_DES3_CRYPT_ECB_ALT were ignored.
This does not concern the implementation provided with Mbed TLS,
where this function cannot fail, or full-module replacements with
MBEDTLS_AES_ALT or MBEDTLS_DES_ALT. Reported by Armelle Duboc in #1092.
