audio: Align bluetooth start behavior

When staring data transfer, if resuming of BT session fails,
the legacy implementation does not indicate an error, thus
causing an automatic retry on next transfer. The AIDL
implementation was switching the stream into an error state
instead. This could cause audio mute when the BT stack is
slow on resuming. This CL aligns AIDL with legacy behavior.
