mm/memory-failure.c: add hwpoison_filter for soft offline
hwpoison_filter is missing in the soft offline path, this leads an issue:
after enabling the corrupt filter, the user process still has a chance to
inject hwpoison fault by madvise(addr, len, MADV_SOFT_OFFLINE) at PFN
which is expected to reject.
Also do a minor change in comment of memory_failure().
