[PATCH] powerpc/mm: remove warning about âtypeâ being set

[Mathieu Malaterre]

âtypeâ is only used when CONFIG_DEBUG_HIGHMEM is set. So add a possibly
unused tag to variable. Remove warning treated as error with W=1:

  arch/powerpc/mm/highmem.c:59:6: error: variable âtypeâ set but not used [-Werror=unused-but-set-variable]
