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.
