[dpdk-dev] [PATCH] crypto/aesni_mb: fix cpu crypto cipher auth

[Fan Zhang <roy.fan.zhang@intel.com>]

This patch fixes the AESNI-MB PMD CPU crypto process function. Orignally
the function tried to access crypto vector's aad buffer even it is not
needed.

Fixes: 8d928d47a29a ("cryptodev: change crypto symmetric vector structure")
