x86/intel_rdt: Modify the intel_pqr_state for better performance
Currently we have pqr_state and rdt_default_state which store the cached CLOSID/RMIDs and the user configured cpu default values respectively. We touch both of these during context switch. Put all of them in one structure so that we can spare a cache line.
