Xiaochen Shen 40fba00ffa x86/resctrl: Do not repeat rdtgroup mode initialization ... When cache allocation is supported and the user creates a new resctrl resource group, the allocations of the new resource group are initialized to all regions that it can possibly use. At this time these regions are all that are shareable by other resource groups as well as regions that are not currently used. The new resource group's mode is also initialized to reflect this initialization and set to "shareable". The new resource group's mode is currently repeatedly initialized within the loop that configures the hardware with the resource group's default allocations. Move the initialization of the resource group's mode outside the hardware configuration loop. The resource group's mode is now initialized only once as the final step to reflect that its configured allocations are "shareable".
