selftests: net: reuseport_dualstack: fix uninitalized parameter
[ Upstream commit d64479a3e3f9924074ca7b50bd72fa5211dca9c1 ]
This test reports EINVAL for getsockopt(SOL_SOCKET, SO_DOMAIN)
occasionally due to the uninitialized length parameter.
Initialize it to fix this, and also use int for "test_family" to comply
with the API standard.
Fixes: d6a61f80b871 ("soreuseport: test mixed v4/v6 sockets")
