    xen/nodemask: Drop any_online_node() and first_unset_node()
    
    These have never been used in Xen, and it is unlikely that they would be
    useful in the future.
    
    any_online_cpu() was dropped by c/s 22bdce1c048 "eliminate first_cpu() etc"
    but the API comment was left in place.  Drop that too.
