[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 */
};
