tools/power/x86/intel-speed-select: turbo-freq auto mode with SMT off

When SMT is disabled from kernel command line, sibling CPUs still
appears in the sysfs as offline CPUs. This is a problem when turbo-freq
is enabled in auto mode. They are still assigned to CLOS value
of 3 as they are still in the present CPU list. But they are not in the
sibling list of a CPU. When the CPU is a high priority CPU, because of
sibling it will be still set to CLOS to 3 as CLOS is assigned at core
level not at CPU level.

So, avoid setting CLOS 3 to offline CPU.
