Muchun Song 3ee2d7471f mm: kfence: fix PG_slab and memcg_data clearing ... It does not reset PG_slab and memcg_data when KFENCE fails to initialize kfence pool at runtime. It is reporting a "Bad page state" message when kfence pool is freed to buddy. The checking of whether it is a compound head page seems unnecessary since we already guarantee this when allocating kfence pool. Remove the check to simplify the code.
