Change the meaning of the combination of -n and -P flags.
Previously, if you used -n to specify a test sending a specified number of bytes and -P to send multiple streams in parallel, iperf3 would send that many bytes on each stream. With this change it just sends the specified total number of bytes regardless of how many streams are used.
