mm/memcg: rename mem_cgroup_split_huge_fixup to split_page_memcg and add nr_pages argument
commit be6c8982e4ab9a41907555f601b711a7e2a17d4c upstream.
Rename mem_cgroup_split_huge_fixup to split_page_memcg and explicitly pass
in page number argument.
In this way, the interface name is more common and can be used by
potential users. In addition, the complete info(memcg and flag) of the
memcg needs to be set to the tail pages.
