[dpdk-dev] [PATCH] crypto/octeontx2: fix sessionless code

[Ankur Dwivedi <adwivedi@marvell.com>]

A temporary session is created for sessionless crypto operations.
rte_cryptodev_sym_session_create() should be used for creating the
temporary session as it initializes the session structure in the
correct way. Also the session should be set to 0 before freeing it.

Fixes: 17ac2a72191b ("crypto/octeontx2: add enqueue/dequeue ops")
