hugetlbfs: fix issue of preallocation of gigantic pages can't work
Preallocation of gigantic pages can't work bacause of commit b5389086 ("hugetlbfs: extend the definition of hugepages parameter to support node allocation"). When nid is NUMA_NO_NODE(-1), alloc_bootmem_huge_page will always return without doing allocation. Fix this by adding more check.
