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.
