mm/memory-failure: simplify put_ref_page()
Patch series "Some cleanups for memory-failure", v3. This series contains a few cleanup patches to avoid exporting unused function, add helper macro, fix some obsolete comments and so on. More details can be found in the respective changelogs. This patch (of 13): Remove unneeded page != NULL check. pfn_to_page() won't return NULL. No functional change intended.
