We don't need to have separate implementations of alloc_hugepage_vma()
for NUMA and non-NUMA. Using variant based on alloc_pages_vma() we would
cover both cases.

This is preparation patch for allocation encrypted pages.

alloc_pages_vma() will handle allocation of encrypted pages. With this
change we don' t need to cover alloc_hugepage_vma() separately.

The change makes typo in Alpha's implementation of
__alloc_zeroed_user_highpage() visible. Fix it too.
