perf kvm: Add pointer to 'perf_kvm_stat' in kvm event

Sometimes, handling kvm events needs to base on global variables, e.g.
when read event counts we need to know the target vcpu ID; the global
variables are stored in structure perf_kvm_stat.

This patch adds add a 'perf_kvm_stat' pointer in kvm event structure,
it is to be used by later refactoring.
