David Hildenbrand 3f982b9b18 mm/hugetlb-cgroup: convert hugetlb_cgroup_css_offline() to work on folios ...

Let's convert hugetlb_cgroup_css_offline() and
hugetlb_cgroup_move_parent() to work on folios.  hugepage_activelist
contains folios, not pages.

While at it, rename page_hcg simply to hcg, removing most of the "page"
terminology.

This removes an unnecessary call to compound_head().
