conf: Change return value of some CPU feature APIs

Browse Source 
The virCPUDefAddFeatureInternal helper function only fails if it is
called with VIR_CPU_ADD_FEATURE_MODE_EXCLUSIVE, which is only used in
virCPUDefAddFeature. The other callers (virCPUDefUpdateFeature and
virCPUDefAddFeatureIfMissing) will never get anything but 0 from
virCPUDefAddFeatureInternal and their return type can be changed to
void.
