include/linux/huge_mm.h declares is_vma_temporary_stack inside an ifdef
CONFIG_TRANSPARENT_HUGEPAGE; however, mm/rmap.c defines the function
unconditionally. Move the function outside of the ifdef.
This eliminates a warning from gcc (-Wmissing-prototypes) and from
Sparse (-Wdecl).
mm/rmap.c:1440:6: warning: no previous prototype for ‘is_vma_temporary_stack’
[-Wmissing-prototypes]
