Joonsoo Kim b226102682 mm, hugetlb: fix and clean-up node iteration code to alloc or free 
Current node iteration code have a minor problem which do one more node
rotation if we can't succeed to allocate.  For example, if we start to
allocate at node 0, we stop to iterate at node 0.  Then we start to
allocate at node 1 for next allocation.

I introduce new macros "for_each_node_mask_to_[alloc|free]" and fix and
clean-up node iteration code to alloc or free.  This makes code more
understandable.
