Drop KVM's odd restriction that disallows clearing CPUID_FAULT in MSR_PLATFORM_INFO if CPL>0 CPUID faulting is enabled in MSR_MISC_FEATURES_ENABLES. KVM generally doesn't require specific ordering when userspace sets MSRs, and the completely arbitrary order of MSRs in emulated_msrs_all means that a userspace that uses KVM's list verbatim could run afoul of the check. Dropping the restriction obviously means that userspace could stuff a nonsensical vCPU model, but that's the case all over KVM. KVM typically restricts userspace MSR writes only when it makes things easier for KVM and/or userspace.
