net.server_epoll: Skip attempt to flush write buffer when not connected

Before 22825cb5dcd8 connection attempts that failed (e.g. connection
refused) would be immediately destroyed.  After, it would schedule
another write cycle and then report 'ondisconnect' again when failing.

Thanks Martin for reporting
