When OpenSSL or AESNI-MB cryptodev is being used in sessionless mode
for symmetric crypto operation (e.g. SHA256 hash), the driver prints
error message:

    CRYPTODEV: set_sym_session_private_data() line 489:
               Set private data for driver 0 not allowed

Then, AESNI-MB driver segfaults in post_process_mb_job().
