532a46b989 KVM: SVM: Add tracepoint for skinit instruction
This patch adds a tracepoint for the event that the guest
executed the SKINIT instruction. This information is
important because SKINIT is an SVM extenstion not yet
implemented by nested SVM and we may need this information
for debugging hypervisors that do not yet run on nested SVM.

nested #vmexit is injected because kvm wants to inject an
interrupt into the guest.
