[dpdk-dev] [PATCH v2] app/test-crypto-perf: fix segmentation fault when use qat pmd

[Slawomir Mrozowicz <slawomirx.mrozowicz@intel.com>]

Fix segmentation fault happened when use QAT PMD's kasumi, snow3g or zug
algorithm to do cipher-then-auth performance test application.
The mentioned algorithms required authentication key data be set.
This patch fix issue that gmac algorithm required authentication key data
be set value equal to cipher key data.

Fixes: f8be1786b1b8 ("app/crypto-perf: introduce performance test application")

v2 changes:
- kasumi, snow3g or zug have differ auth and cipher key data
