mm/hwpoison-inject: check PageLRU of hpage
Hwpoison injector checks PageLRU of the raw target page to find out whether the page is an appropriate target, but current code now filters out thp tail pages, which prevents us from testing for such cases via this interface. So let's check hpage instead of p.
