[PATCH] media: mtk-jpeg: Fix a reference count leak.

[wu000273]

From: Qiushi Wu <wu000273@xxxxxxx>

pm_runtime_get_sync() increments the runtime PM usage counter even
when it returns an error code. Thus call pm_runtime_put_noidle()
if pm_runtime_get_sync() fails.

Fixes: b2f0d2724ba4 ("[media] vcodec: mediatek: Add Mediatek JPEG Decoder Driver")
