Subject: [PATCH 26/58] mm/internal.h: Declare vma_address unconditionally

mm/internal.h declares vma_address 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:527:1: warning: no previous prototype for ‘vma_address’ [-Wmissing-prototypes]
