Subject: [PATCH] crypto/aesni_mb: fix invalid session error

[ upstream commit 6fcd9fdf379b8218202e7213623da9b7359bb518 ]

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")
