KVM: SVM: Sync guest's PERF_CNTR_GLOBAL_CTL from h/w only on successful VMRUN
Don't (re)read PERF_CNTR_GLOBAL_CTL from hardware on a failed VMRUN, as the
purpose of the read is to synchronize KVM's cache with any writes done by
the guest, and the guest can't possibly have modified the MSR if it never
got a chance to run.
