ASoC: SOF: topology: fix get control data return type and arguments
sof_get_control_data returns negative values even though the return value is defined unsigned (size_t). So change the return value type to int and add the data size as pointer argument to sof_get_control_data to avoid ambiquity in the meaning of the return type.
