I find it a bit confusing that in qat_sym_pmd.c, session_pool was not 
set when sym qp was setup, as shown below.

static int qat_sym_qp_setup(struct rte_cryptodev *dev, uint16_t qp_id,
     const struct rte_cryptodev_qp_conf *qp_conf,
     int socket_id, struct rte_mempool *session_pool __rte_unused)

However, later on when qat sym builds request it explicitly looks for 
session info in qat_sym_build_request(), which ends up with failure.

Did I miss something during device and qp setup? How does qat sym setup 
session info for qp?
