powerpc: Fix pud_mkwrite() definition after pte_mkwrite() API changes

I believe there's one semantic conflict we missed, which breaks the powerpc64
build: recent changes to arch/powerpc/include/asm/book3s/64/pgtable.h created
a new semantic conflict due to the changes to the pte_mkwrite() API:

  161e393c0f63 ("mm: Make pte_mkwrite() take a VMA")

... resolved with the fix below.

Only build tested though.

The crossing upstream commit was:

  27af67f35631 ("powerpc/book3s64/mm: enable transparent pud hugepage")
