ASoC: SOF: topology: Fix memory leak in sof_control_load()
scontrol doesn't get freed when kstrdup returns NULL.
Fix by free iscontrol in that case.
scontrol = kzalloc(sizeof(*scontrol), GFP_KERNEL);
if (!scontrol)
return -ENOMEM;
scontrol->name = kstrdup(hdr->name, GFP_KERNEL);
if (!scontrol->name)
return -ENOMEM;
