test/perf/passt_tcp: Drop iperf3 window size for host-to-guest tests
With a recent 5.15 kernel, passing a huge window size to iperf3 with
lower MTUs makes iperf3 stop sending packets after a few seconds --
I haven't investigated this in detail, but the window size will be
adjusted dynamically anyway and not passing it doesn't actually
affect throughput, so simply drop the option.
