nodemask.h: remove macro any_online_node 

The macro any_online_node() is prone to producing sparse warnings due to
the local symbol 'node'.  Since all the in-tree users are really
requesting the first online node (the mask argument is either
NODE_MASK_ALL or node_online_map) just use the first_online_node macro and
remove the any_online_node macro since there are no users.
