KVM: x86/pmu: Clear anythread deprecated bit when 0xa leaf is unsupported on the SVM
The AMD platform does not support the functions Ah CPUID leaf. The returned
results for this entry should all remain zero just like the native does:
AMD host:
0x0000000a 0x00: eax=0x00000000 ebx=0x00000000 ecx=0x00000000 edx=0x00000000
(uncanny) AMD guest:
0x0000000a 0x00: eax=0x00000000 ebx=0x00000000 ecx=0x00000000 edx=0x00008000
Fixes: cadbaa039b99 ("perf/x86/intel: Make anythread filter support conditional")
