[PATCH v2 07/13] mm/memory-failure: simplify unneeded hwpoison_filter() variant

[Miaohe Lin <linmiaohe@huawei.com>]

When CONFIG_HWPOISON_INJECT is not enabled, there is no user of the
hwpoison_filter() outside memory-failure. So there is no need to export
it and we can further make it 'static' and 'inline'.
