arch/x86/kernel/setup.c: fixup rh_check_supported
With 8078f4d6102f9 ('x86/cpu/topology: Rename smp_num_siblings') and
89b0f15f408f7 ('x86/cpu/topology: Get rid of cpuinfo::x86_max_cores')
the RHEL only rh_check_supported() needs updated to also replaced
boot_cpu_data.x86_max_cores and smp_num_siblings.
