BUILD: http-client: Avoid dead code when compiled without SSL support

When an HTTP client is started on an HAProxy compiled without the SSL
support, an error is triggered when HTTPS is used. In this case, the freshly
created conn-stream is released. But this code is specific to the non-SSL
part. Thus it is moved the in right #if/#else section.

This patch should fix the issue #1655.
