Subject: 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.
