[PATCH v3 17/17] mm/hugetlb: localize HUGE_BOOTMEM_ZONES_VALID

HUGE_BOOTMEM_ZONES_VALID is only used by the huge_bootmem_page flag
handling in mm/hugetlb.c. Keep the definition next to that private data
structure instead of exposing it through the public hugetlb header.

No functional change is intended.
