Subject: [PATCH] savePreset() error case bugfix
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Keeps the status machine coherent: no spurious async save, no lost pending playlist write, no change to successful paths.
* Aligns behavior with the already corrected mutex‑failure path, making both early exits consistent.
