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.
