Additional connections reuse. If ngx_drain_connections() fails to immediately reuse any connections and there are no free connections, it now additionally tries to reuse a connection again. This helps to provide at least one free connection in case of HTTP/2 with lingering close, where merely trying to reuse a connection once does not free it, but makes it reusable again, waiting for lingering close.
