[Devel] [PATCH vz10 01/15] selftests/cgroup: fix -Wmaybe-uninitialized warning in test_numa_migrate

[Konstantin Khorenko]

  test_numa_migrate.c: In function 'parse_memory_numa_stat.isra':
  test_numa_migrate.c:521:34: warning: 'node' may be used uninitialized [-Wmaybe-uninitialized]
    521 |                         node_stat[node] = node_bytes;
        |                                  ^
  test_numa_migrate.c:485:16: note: 'node' was declared here
    485 |         size_t node;
        |                ^~~~

Initialize 'node' to 0 to silence the -Wmaybe-uninitialized warning.
The variable is always set inside the loop before use in the else branch,
but GCC cannot prove this statically.
