Subject: [PATCH bpf-next] bpf, selftests: fix test_maps now that sockmap supports UDP

UDP socket support was added recently so testing UDP insert failure is no
longer correct and causes test_maps failure. The fix is easy though, we
simply need to test that UDP is correctly added instead of blocked.
