mm/huge_memory: fix comment of page_deferred_list
The current comment is confusing because if global or memcg deferred list
in the second tail page is occupied by compound_head, why we still use
page[2].deferred_list here? I think it wants to say that Global or memcg
deferred list in the first tail page is occupied by compound_mapcount and
compound_pincount so we use the second tail page's deferred_list instead.
