Volume Rocker: Do not wake up during track seek.

* After switching to Audioservice track seek works great but it woke the device too if we select both options. Wake only if we do not skip tracks (like raising the volume).

Fix: Linked volumes

Check for linked volumes a little earlier than we previously did.
This ensures the correct value is set after boot.
