Alberts Muktupāvels 84819a350d 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.
