If we use one cpu from an object, then we will get a NULL response if we ask for the next object of that type within the remaining cpuset since not all of the cpus in the object are still available. This problem resulted from the recent change to only use available cpus in PRRTE topologies. So instead scan across the cpus, check to see if it is inside the object of interest - if so, then we can bind to that cpu, if not then we keep searching.
