hugetlb: split hugetlb_hstate_alloc_pages

1G and 2M huge pages have different allocation and initialization logic,
which leads to subtle differences in parallelization.  Therefore, it is
appropriate to split hugetlb_hstate_alloc_pages into gigantic and
non-gigantic.

This patch has no functional changes.
