crypto/octeontx2: fix session-less mode

Browse Source 
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.
