mm/hugetlb: move huge_boot_pages list init to hugetlb_bootmem_alloc

Browse Source 
Instead of initializing the per-node hugetlb bootmem pages list from the
alloc function, we can now do it in a somewhat cleaner way, since there is
an explicit hugetlb_bootmem_alloc function.  Initialize the lists there.
