[PATCH 4/5] mm: Check for page poison in both page_to_nid implementations

[Matthew Wilcox <willy@infradead.org>]

From: "Matthew Wilcox (Oracle)" <willy@infradead.org>

The earlier patch that added page poison checking in page_to_nid()
only modified one implementation; both configuration options should
have this check.
