Updated as below

    hugetlb: add charge/uncharge calls for HugeTLB alloc/free
    
    This adds necessary charge/uncharge calls in the HugeTLB code. We do
    memcg charge in page alloc and uncharge in compound page destructor.
    We also need to ignore HugeTLB pages in __mem_cgroup_uncharge_common
    because that get called from delete_from_page_cache
