x86/intel_rdt: Fix setting of closid when adding CPUs to a group There was a cut & paste error when adding code to update the per-cpu closid when changing the bitmask of CPUs to an rdt group. The update erronously assigns the closid of the default group to the CPUs which are moved to a group instead of assigning the closid of their new group. Use the proper closid.
