The volume and bytes kcontrols are currently not freeing their
memory on initialization failures. When an error occurs, all the
widgets loaded so far are unloaded via sof_widget_unload().
But this only happens for the widgets that got successfully loaded.
Fix that by kfree()-ing the allocated memory on load error.
