[PATCH 1/2] KVM: vmx/pmu: Fix dummy check if lbr_desc->event is created

[Like Xu]

If lbr_desc->event is successfully created, the intel_pmu_create_
guest_lbr_event() will return 0, otherwise it will return -ENOENT,
and then jump to LBR msrs dummy handling.

Fixes: 1b5ac3226a1a ("KVM: vmx/pmu: Pass-through LBR msrs when the guest LBR 
event is ACTIVE")
