[dpdk-dev] [PATCH] crypto/qat: fix NULL authentication request

[Adam Dybkowski]

This patch fixes the NULL auth generation case where the request
shouldn't contain the authentication result address. Allows to run
ipsec_autotest with a QAT device.

Fixes: 65beb9abca6d ("crypto/qat: fix null auth when using VFIO")
