Paolo Bonzini 88e4cd893f KVM x86/pmu fixes for 6.6:
- Truncate writes to PMU counters to the counter's width to avoid spurious
    overflows when emulating counter events in software.
 
  - Set the LVTPC entry mask bit when handling a PMI (to match Intel-defined
    architectural behavior).
 
  - Treat KVM_REQ_PMI as a wake event instead of queueing host IRQ work to
    kick the guest out of emulated halt.
