Subject: [PATCH bpf-next] selftests/bpf: properly initialize linfo in sockmap_basic

When using -Werror=missing-braces, compiler complains about missing braces.
Let's use use ={} initialization which should do the job:

tools/testing/selftests/bpf/prog_tests/sockmap_basic.c: In function 'test_sockmap_iter':
tools/testing/selftests/bpf/prog_tests/sockmap_basic.c:181:8: error: missing braces around initializer [-Werror=missing-braces]
  union bpf_iter_link_info linfo = {0};
        ^
tools/testing/selftests/bpf/prog_tests/sockmap_basic.c:181:8: error: (near initialization for 'linfo.map') [-Werror=missing-braces]
tools/testing/selftests/bpf/prog_tests/sockmap_basic.c: At top level:
