KVM: x86: Add RIP to the kvm_entry, i.e. VM-Enter, tracepoint
Add RIP to the kvm_entry tracepoint to help debug if the kvm_exit
tracepoint is disabled or if VM-Enter fails, in which case the kvm_exit
tracepoint won't be hit.
Read RIP from within the tracepoint itself to avoid a potential VMREAD
and retpoline if the guest's RIP isn't available.
