Skip this expect_errno when must_fail is false too in connect_fd_to_addr(). connect_fd_to_fd() returns "0" when connect() fails but "expect_errno" matched. So "err" is "0" after invoking connect_fd_to_fd() in run_lookup_test(). "err = -errno" is needed to get the real error number before checking value of "err".
