mm: fix typo in mm.h when NODE_NOT_IN_PAGE_FLAGS
NODE_NOT_IN_PAGE_FLAGS is defined in mm.h when the node information is not stored in the page flags bitmap. Unfortunately, there's a typo in one of the checks for it. This patch fixes it (s/NODE_NOT_IN_PAGEFLAGS/NODE_NOT_IN_PAGE_FLAGS/). Since this has been around for ages, I doubt it's been causing any serious problems.
