Subject: [PATCH] mm/hwpoison-inject.c: change permission of
 corrupt-pfn/unpoison-pfn to 0200

Hwpoison injection doesn't implement read method for
corrupt-pfn/unpoison-pfn attributes:

# cat /sys/kernel/debug/hwpoison/corrupt-pfn
cat: /sys/kernel/debug/hwpoison/corrupt-pfn: Permission denied
# cat /sys/kernel/debug/hwpoison/unpoison-pfn
cat: /sys/kernel/debug/hwpoison/unpoison-pfn: Permission denied

This patch changes the permission of corrupt-pfn/unpoison-pfn to 0200.
