#48 Cannot handle more than 127 connections

[Olivier MATZ]

When running iperf client with -P x with x > 127, the sum of bandwidth is not displayed at the end of the test.
The attached patch fixes the issue.

To reproduce the problem:

SUCCESS
$ iperf -s -p 4000
# on another terminal of the same machine
$ iperf -c 127.0.0.1 -p 4000 -P 100 -t 2

FAIL
$ iperf -s -p 4000
# on another terminal of the same machine
$ iperf -c 127.0.0.1 -p 4000 -P 200 -t 2
