[dpdk-dev] [PATCH] crypto/aesni_mb: fix invalid session error

[Sergio Gonzalez Monroy <sergio.gonzalez.monroy@intel.com>]

Setting an invalid session in the crypto op results in SEGFAULT because
the JOB user_data was never set to the crypto op.

Fixes: 0f548b50a160 ("crypto/aesni_mb: process crypto op on dequeue")
