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
