[PATCH] crypto/openssl: fix SM2 for older openssl version

[Ciara Power]

Currently when configuring the session for SM2 asym on OpenSSL PMD using
an older OpenSSL version than 3.0, an error returns,
showing a failure status for tests.

This should skip tests, as the SM2 support is for OpenSSL version 3.0+.

Fixes: 3b7d638fb11f ("crypto/openssl: support asymmetric SM2")
