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.
Fixes: cac974a51ebb ("ASoC: SOF: topology: use set_get_data in process load")
