Analyze and fix the following issue in the Linux kernel code: KVM: SVM: Don't intercept IRET when injecting NMI and vNMI is enabled
Problem Details: When vNMI is enabled, rely entirely on hardware to correctly handle NMI blocking, i.e. don't intercept IRET to detect when NMIs are no longer blocked. KVM already correctly ignores svm->nmi_masked when vNMI is enabled, so the effect of the bug is essentially an unnecessary VM-Exit. KVM intercepts IRE...

Problem Details: Don't force a masterclock update when a vCPU synchronizes to the current TSC generation, e.g. when userspace hotplugs a pre-created vCPU into the VM.
