crypto/aesni_mb: fix zero burst dequeue

Browse Source 
In the unlikely scenario that an application
calls rte_cryptodev_dequeue_burst with nb_ops = 0,
there was a job leak, as a job would be created
but would not be populated, as no operation is passed.

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