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. https://bugzilla.gnome.org/show_bug.cgi?id=752244
