    gvc-mixer-stream: make card-index unsigned int
    
    Card in pa_source_info that is used as card-index is uint32_t so it
    is never less then 0. Also index in GvcMixerCard is already unsigned
    int that is used to compare with card-index. This fixes build
    warning - comparison between signed and unsigned integer expressions.
