[dpdk-dev] [PATCH] crypto/qat: fix authentication offset and length for GMAC

[Arek Kusztal <arkadiuszx.kusztal@intel.com>]

Authentication length and offset need to be set like for any other
authentication algorithms as it no longer uses aad pointer

Fixes: b79e4c00af0e ("cryptodev: use AES-GCM/CCM as AEAD algorithms")
