KVM: SVM: Update control fields on #VMEXIT if and only if VMRUN succeeded
Leave control.erap_ctl and control.clean as-is in the VMCS if VMRUN fails,
because as per AMD:
there's no explicit architectural guarantee about the behavior in the
presence of VMRUN failures. So the best thing to do would be to assume
that if VMRUN fails, the actions requested in the control fields may not
have been performed.
