perf/x86/intel: KVM: Handle cross-mapped PEBS PMCs entirely within KVM
Now that perf operates on a KVM-provided snapshot of PMU state, handled
cross-mapped PEBS counters entirely in KVM by clearing unusable counters
from the to-be-enabled mask instead of foisting the work on perf.
No functional change intended.
