[PATCH -mmotm] mm/memory-failure: remove stub function

[Randy Dunlap <rdunlap@xxxxxxxxxxxxx>]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

This stub is no longer needed since the function is no longer
inside an #ifdef/#endif block.

Fixes this build error:

../mm/memory-failure.c:180:13: error: redefinition of ‘page_handle_poison’
