KVM: x86: handle MSR_IA32_DEBUGCTLMSR with report_ignored_msrs
Windows2016 guest tries to enable LBR by setting the corresponding bits
in MSR_IA32_DEBUGCTLMSR. KVM does not emulate MSR_IA32_DEBUGCTLMSR and
spams the host kernel logs with error messages like:
kvm [...]: vcpu1, guest rIP: 0xfffff800a8b687d3 kvm_set_msr_common: MSR_IA32_DEBUGCTLMSR 0x1, nop"
This patch fixes this by enabling error logging only with
'report_ignored_msrs=1'.
