Like Xu 67b45af946 KVM: vmx/pmu: Fix dummy check if lbr_desc->event is created 
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: 1b5ac3226a ("KVM: vmx/pmu: Pass-through LBR msrs when the guest LBR event is ACTIVE")
