    gvc-mixer-control: Really fix double-free when setting headset
    
    In a28e23d9006a32c8982ad8bda11fec131c6b36e8, we said:
    The callbacks will be called repeatedly, once with data, and later
    on with eol == 0. Make sure to only free it when we get the eol call
    instead of once we've applied the settings.
    
    Whereas the docs say:
    When requesting all of these [instances] at once, the callback will be
    called multiple times, once for each object. When the list has been
    exhausted, the callback will be called without an information structure
    and the eol parameter set to a positive value.
    
    If an error occurs, the callback will be invoked without an information
    structure and eol set to a negative value.
    
    So, in all, we need to free our callback data when eol is positive, or
    negative. So, when it's not 0.
    
    Seems we got lucky in the original commit because the test machine only
    had a single soundcard.
