ASoC: SOF: topology: Fix memory leak of scontrol->name
The scontrol->name is allocated with kstrdup, it must be freed before the
scontrol is freed to avoid leaking memory.
The constant leaking happens via sof_widget_unload() path on every module
removal.
Fixes: b5cee8feb1d48 ("ASoC: SOF: topology: Make control parsing IPC agnostic")
