[PATCH 13/23] powerpc/hugetlb: pte_alloc_huge()

pte_alloc_map() expects to be followed by pte_unmap(), but hugetlb omits
that: to keep balance in future, use the recently added pte_alloc_huge()
instead. huge_pte_offset() is using __find_linux_pte(), which is using
pte_offset_kernel() - don't rename that to _huge, it's more complicated.
