net.server_epoll: Fix streaming downloads (thanks Menel) ff4e34c448a4 broke the way net.http.server streams downloads from disk because it made writes from the ondrain callback no longer reset the want-write flag, causing the download to halt. Writes from the predrain handler still must not trigger anything but additions to the buffer, since it is about to do all the socket writing already.
