virDomainEventCallbackListFree: Don't leak @list->callbacks
virDomainEventCallbackListFree: Don't leak @list->callbacks

The @list->callbacks is an array that is inflated whenever a new event
is added, e.g. via virDomainEventCallbackListAddID(). However, when we
are freeing the array, we free the items within it but forgot to
actually free it.
