mm, hugetlb, soft_offline: use new_page_nodemask for soft offline migration
new_page is yet another duplication of the migration callback which has to handle hugetlb migration specially. We can safely use the generic new_page_nodemask for the same purpose. Please note that gigantic hugetlb pages do not need any special handling because alloc_huge_page_nodemask will make sure to check pages in all per node pools. The reason this was done previously was that alloc_huge_page_node treated NO_NUMA_NODE and a specific node differently and so alloc_huge_page_node(nid) would check on this specific node.
