Moving it out of PAUSED without the STOP trigger leaves device state paused, and skipping stop_operating prevents the following sync_stop from cleaning it up. Run the existing STOP and stop_operating path for PAUSED as well as running streams. This replaces the earlier v7 proposal which only marked stop_operating. Drivers now receive STOP when a paused stream is dropped or stopped by an error. The change affects all PCM drivers. Playback pause/drop/prepare/write and capture lifecycle tests exercise the change. Physical drivers beyond virtio-snd still need review and testing.
