SSL: fixed potential leak on memory allocation errors. If ngx_pool_cleanup_add() fails, we have to clean just created SSL context manually, thus appropriate call added. Additionally, ngx_pool_cleanup_add() moved closer to ngx_ssl_create() in the ngx_http_ssl_module, to make sure there are no leaks due to intermediate code.
