PATCH 1/3 app/crypto-perf: use right API to free session

Use the right API for session freeing. Sessions can be asymmetric, symmetric or security.

PATCH 2/3 app/crypto-perf: fix invalid SPI

As per IPsec specification (RFC 4303) SPI zero is reserved. Using lcore_id directly would mean SPI 0 would also be attempted. This may lead to failure on an otherwise compliant implementation.

PATCH 3/3 app/crypto-perf: fix IPsec direction

In reply to Anoob Joseph

The default value of options->auth_op & options->cipher_op are such that an unconditional check for the same would always return true. Hence, the direction is always determined to be outbound/egress.

The field options->aead_algo should be checked prior to checking above fields. Since the same check would be required in datapath, introduce a new flag in options for the same.
