x86/CPU/AMD: Fix Zen SMT topology
commit 08b259631b5a1d912af4832847b5642f377d9101 upstream.
After:
a33d331761bc ("x86/CPU/AMD: Fix Bulldozer topology")
our SMT scheduling topology for Fam17h systems is broken, because
the ThreadId is included in the ApicId when SMT is enabled.
So, without further decoding cpu_core_id is unique for each thread
rather than the same for threads on the same core. This didn't affect
systems with SMT disabled. Make cpu_core_id be what it is defined to be.

testing stock @65watt TDP (1700) is pointless testing stock @95watt TDP (1700X) on AIR cooling is a good start.
Especially one can expect big fail on current released Ubuntus So much about world record, just forget about it really
