mm, hwpoison: make unpoison aware of raw error info in hwpoisoned hugepage
Raw error info list needs to be removed when hwpoisoned hugetlb is
unpoisoned. And unpoison handler needs to know how many errors there are
in the target hugepage. So add them.
HPageVmemmapOptimized(hpage) and HPageRawHwpUnreliable(hpage)) sometimes
can't be unpoisoned, so skip them.
