[PATCH] KVM: X86: Enable IA32_MSIC_ENABLE MONITOR bit when exposing mwait/monitor

From: Wanpeng Li MSR IA32_MSIC_ENABLE bit 18, according to SDM: | When this bit is set to 0, the MONITOR feature flag is not set (CPUID.01H:ECX[bit 3] = 0). | This indicates that MONITOR/MWAIT are not supported. | | Software attempts to execute MONITOR/MWAIT will cause #UD when this bit
