memcg: change page_cgroup_zoneinfo signature
Instead of passing a whole struct page_cgroup to this function, let it
take only what it really needs from it: the struct mem_cgroup and the
page.
This has the advantage that reading pc->mem_cgroup is now done at the same
place where the ordering rules for this pointer are enforced and
explained.
It is also in preparation for removing the pc->page backpointer.
