Fix behavior of unspecified number of requests for OCSP responder to match documentation

[aeijdenberg]

Documentation states that "-nrequest pnum Number of requests to accept (default unlimited)", but in practice not specifying "-nrequest" would have the affect of accepting only 1 request.

I'm going to d othis:

        /* If not unlimited, see if we took all we should. */
        if (accept_count != -1 && --accept_count <= 0) {
            ret = 0;
            goto end;
        }
