Subject: [PATCH] monitors: disable stream-restore for device loopback nodes

stream-restore should not be touching node properties of the Bluetooth
mic / device set / offload / ALSA UCM split loopback nodes. Those are
controlled by Route settings on the device.

Set device.routes and state.restore-props=false as appropriate to avoid
that.
