hugetlb: rework hstate_next_node_* functions
Modify the hstate_next_node* functions to allow them to be called to
obtain the "start_nid". Then, whereas prior to this patch we
unconditionally called hstate_next_node_to_{alloc|free}(), whether or not
we successfully allocated/freed a huge page on the node, now we only call
these functions on failure to alloc/free to advance to next allowed node.
Factor out the next_node_allowed() function to handle wrap at end of
node_online_map. In this version, the allowed nodes include all of the
online nodes.
