Alexandre Ghiti 4eb0716e86 hugetlb: allow to free gigantic pages regardless of the configuration ...

On systems without CONTIG_ALLOC activated but that support gigantic pages,
boottime reserved gigantic pages can not be freed at all.  This patch
simply enables the possibility to hand back those pages to memory
allocator.
