Thomas Gleixner 2066f00e5b x86/topology: Implement topology_is_core_online() to address SMT regression 
Christian reported that commit a430c11f40 ("intel_idle: Rescan "dead" SMT
siblings during initialization") broke the use case in which both 'nosmt'
and 'maxcpus' are on the kernel command line because it onlines primary
threads, which were offline due to the maxcpus limit.

The initially proposed fix to skip primary threads in the loop is
inconsistent. While it prevents the primary thread to be onlined, it then
onlines the corresponding hyperthread(s), which does not really make sense.

The CPU iterator in cpuhp_smt_enable() contains a check which excludes all
threads of a core, when the primary thread is offline. The default
implementation is a NOOP and therefore not effective on x86.

Implement topology_is_core_online() on x86 to address this issue. This
makes the behaviour consistent between x86 and PowerPC.
