  The application may want to store private data along with the
rte_crypto_op that is transparent to the rte_cryptodev layer.
For e.g., If an eventdev based application is submitting a
crypto session-less operation and wants to indicate event
information required to construct a new event that will be
enqueued to eventdev after completion of the crypto
operation. This patch provides a mechanism for the application
to associate this information with the rte_crypto_op in
session-less mode.
