Bootmem HugeTLB pages currently defer HVO setup to
hugetlb_vmemmap_init_late(), because the optimization needs zone
information.

Now that zone initialization is available earlier, the bootmem HVO setup
can be done directly from hugetlb_vmemmap_init_early(). This lets
gigantic HugeTLB pages apply HVO as soon as they are allocated.

Bootmem gigantic pages that span multiple zones are now filtered out
when they are allocated, so the remaining bootmem gigantic pages seen by
later hugetlb initialization are already zone-valid. As a result,
hugetlb_vmemmap_init_late() no longer needs to handle bootmem HVO setup.
