It requires to change "struct rte_cryptodev_sym_session" to store more
than one private data for devices, as well as remove redundant dev_id
and dev_type.
Effected public functions:
- rte_cryptodev_sym_session_pool_create
- rte_cryptodev_sym_session_create
- rte_cryptodev_sym_session_free
While session will not be directly associated with device, followed API
will be changed adding uint8_t dev_id to the argument list:
- rte_cryptodev_queue_pair_attach_sym_session
- rte_cryptodev_queue_pair_detach_sym_session
