audio: Only replace route info when Bluetooth device is bonded

This fixes a bug that causes non-Bluetooth devices with an `address` to
have their routeId and deviceName replaced with null.

The bug is fixed by detecting if the given AudioDeviceInfo is a bonded
Bluetooth device before attempting to replace its info.
