KVM: x86/pmu: Correct the mask used in a pmu event filter lookup
When checking if a pmu event the guest is attempting to program should
be filtered, only consider the event select + unit mask in that
decision. Use an architecture specific mask to mask out all other bits,
including bits 35:32 on Intel. Those bits are not part of the event
select and should not be considered in that decision.
