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

[Slawomir Mrozowicz]

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 value
equal to cipher key data.

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