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

[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.

Fixes: 28dde5da503e ("app/crypto-perf: support lookaside IPsec")
