KVM: x86: Enable CMCI capability by default and handle injected UCNA errors

Browse source

This patch enables MCG_CMCI_P by default in kvm_mce_cap_supported. It
reuses ioctl KVM_X86_SET_MCE to implement injection of UnCorrectable
No Action required (UCNA) errors, signaled via Corrected Machine
Check Interrupt (CMCI).

Neither of the CMCI and UCNA emulations depends on hardware.
