[Anoob] Shouldn't we make this a union? In symmetric mode, it is done that way and it makes sense also.

Something like,

       RTE_STD_C11
       union {
               struct rte_cryptodev_asym_session *session;
               /**< Handle for the initialised session context */
               struct rte_crypto_asym_xform *xform;
               /**< Session-less API crypto operation parameters */
       };
