powerpc/mm: Fix "sz" set but not used warning 

Fix compiler warning:
  arch/powerpc/mm/hugetlbpage-hash64.c: In function '__hash_page_huge':
  arch/powerpc/mm/hugetlbpage-hash64.c:29:28: warning: variable 'sz' set
  but not used [-Wunused-but-set-variable]

mpe: The last usage of sz was removed in 0895ecda79 ("powerpc/mm:
Bring hugepage PTE accessor functions back into sync with normal
accessors").
