Disabled SSL certificate verify

[Ruan Linqi]

 Hi developers:
      We made a large scale security static analysis on several open source projects, and found some mistakes in dnsval-2.0. In the @libval/valdane.c:743:
   int val_dane_check(val_context_t *ctx,SSL *con,struct val_danestatus *danestatus,int *do_pathval)
  {
       [...]
       switch (dane_cur->usage) {
       [...]
       case DANE_USE_SVC_CONSTRAINT: /*1*/
           cert = SSL_get_peer_certificate(con);
           cert_datalen = i2d_X509(cert, NULL);
       [...]
  }

     In this function,you do cert verify . But the API SSL_get_peer_certificate and SSL_get_verify_result do not in the same case.There may exist some problem?
