Subject: [PATCH] Fix doing rsa-me, altough rsa-crt would be possible

rsa-crt is preferred to rsa-me when possible for performance reason.
This bug was introduced with commit dc8465b (ibmca >= 1.3.1) for
openssl >= 1.1.0. Commit ed496f6 (ibmca >= 2.0.0) introduced the bug
also for openssl versions < 1.1.0.
