hugetlb: use vmf_anon_prepare() instead of anon_vma_prepare()

Browse source

hugetlb_no_page() and hugetlb_wp() call anon_vma_prepare().  In
preparation for hugetlb to safely handle faults under the VMA lock, use
vmf_anon_prepare() here instead.

Additionally, passing hugetlb_wp() the vm_fault struct from
hugetlb_fault() works toward cleaning up the hugetlb code and function
stack.
