powerpc/mm/hash/4k: Free hugetlb page table caches correctly.
With 4k page size for hugetlb we allocate hugepage directories from its on slab
cache. With patch 0c4d26802 ("powerpc/book3s64/mm: Simplify the rcu callback for page table free")
we missed to free these allocated hugepd tables.
Update pgtable_free to handle hugetlb hugepd directory table.
Fixes: 0c4d268029bf ("powerpc/book3s64/mm: Simplify the rcu callback for page table free")
