When compiling the selftests, the following error is printed out:
selftests/bpf/prog_tests/changes_pkt_data.c: In function ‘test_aux’:
selftests/bpf/prog_tests/changes_pkt_data.c:22:27: error: ‘main’ is usually a function [-Werror=main]
  struct changes_pkt_data *main = NULL;
                           ^~~~

Fix it by replacing with 'main_data'.
