Subject: mm/hwpoison: disable hwpoison filter during removing
hwpoison filter is enabled by hwpoison-inject module, after removing this
module, hwpoison filter still works. What is worse, user can not find the
debugfs entries to know this.
Disable the hwpoison filter during removing hwpoison-inject module.
