selftests: mptcp: Initialize variables to quiet gcc 12 warnings
commit fd37c2ecb21f7aee04ccca5f561469f07d00063c upstream.
In a few MPTCP selftest tools, gcc 12 complains that the 'sock' variable
might be used uninitialized. This is a false positive because the only
code path that could lead to uninitialized access is where getaddrinfo()
fails, but the local xgetaddrinfo() wrapper exits if such a failure
occurs.
Initialize the 'sock' variable anyway to allow the tools to build with
gcc 12.
Fixes: 048d19d444be ("mptcp: add basic kselftest for mptcp")

[ mptcp_inq.c and mptcp_sockopt.c are not in this version. The fix can
still be applied in mptcp_connect.c without conflicts. ]
