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;
