Maxim Levitsky 06ef813466 KVM: SVM: avoid refreshing avic if its state didn't change ...

Since AVIC can be inhibited and uninhibited rapidly it is possible that
we have nothing to do by the time the svm_refresh_apicv_exec_ctrl
is called.

Detect and avoid this, which will be useful when we will start calling
avic_vcpu_load/avic_vcpu_put when the avic inhibition state changes.
