bluez5: temporarily remove BAP nodes when another device is switching

Browse source 
Unicast BAP codec switch requires CIG reconfiguration, which cannot be
done if there is an acquired transport.

When doing BAP codec switch, disable nodes of other devices sharing the
same CIG.

To avoid problems with node start/stop, just remove and re-add them.
