Unreachable code in SSL certificate check logic

Hi, 

There is an unreachable branch in `TSSLSocketWithWildcardSAN #73`s

```

1. Line73: This branch will never be reached
   raise TTransportException(
   type=TTransportException.UNKNOWN,
   message='Could not validate SSL certificate from '
   'host "%s". Cert=%s' % (self.host, cert)) 

```

Can I fix it ?
