Vitaly Kuznetsov 9439fabfc3 KVM: x86: Drop guest CPUID check for host initiated writes to MSR_IA32_PERF_CAPABILITIES
[ Upstream commit 1aa2abb33a419090c7c87d4ae842a6347078ee12 ]

The ability to write to MSR_IA32_PERF_CAPABILITIES from the host should
not depend on guest visible CPUID entries, even if just to allow
creating/restoring guest MSRs and CPUIDs in any sequence.
