Subject: [PATCH v1 net 3/5] selftest: tcp: Fix address length in bind_wildcard.c.

The selftest passes the IPv6 address length for an IPv4 address.
We should pass the correct length.

Note inet_bind_sk() does not check if the size is larger than
sizeof(struct sockaddr_in), so there is no real bug in this
selftest.

Fixes: 13715acf8ab5 ("selftest: Add test for bind() conflicts.")
