Subject: HWPOISON: change order of error_states[]'s elements
error_states[] has two separate states "unevictable LRU page" and "mlocked
LRU page", and the former one has the higher priority now. But because of
that the latter one is rarely chosen because pages with PageMlocked highly
likely have PG_unevictable set. On the other hand, PG_unevictable without
PageMlocked is common for ramfs or SHM_LOCKed shared memory, so reversing
the priority of these two states helps us clearly distinguish them.
