Paolo Bonzini 01edb1cfbd KVM x86 PMU changes for 6.8:

- Fix a variety of bugs where KVM fail to stop/reset counters and other state
    prior to refreshing the vPMU model.
 
  - Fix a double-overflow PMU bug by tracking emulated counter events using a
    dedicated field instead of snapshotting the "previous" counter.  If the
    hardware PMC count triggers overflow that is recognized in the same VM-Exit
    that KVM manually bumps an event count, KVM would pend PMIs for both the
    hardware-triggered overflow and for KVM-triggered overflow.
