[dpdk-dev] [PATCH] cryptodev: remove crypto operation status value

[Kirill Rybalchenko]

Crypto operation status RTE_CRYPTO_OP_STATUS_ENQUEUED is removed
from rte_crypto.h as it is not needed for crypto operation processing.
This status value is redundant to RTE_CRYPTO_OP_STATUS_NOT_PROCESSED value
and it was not intended to be part of public API.
