[dpdk-users] crypto device 'crypto_aesni_mb' doesn't work in secondary process

when the crypto device of type 'crypto_aesni_mb' is

created in the primary process a secondary process

crashes when writing into the encryption queue.

The dequeue function rte_cryptodev_dequeue_burst()

crashes in flush_mb_mgr() when it tries to access the

structure of function pointers qp->op_fns.

The reason is that this structure is allocated by the

primary process in its memory which is not accessible

in the secondary process (of course also the function

pointers are pointing to code of the primary process).
