[PATCH v2 1/4] ws2_32/tests: Use %u and %zu in test_ipv6_cmsg instead of casting

Hi,

While running your changed tests, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?

Full results can be found at:
