OM2000: Send ALTCRQ for SuperChannel after receiving IS Enable Req Ack
When the BTS is configured to use a SuperChannel and it is using a
unix domain socket based transport towards the L2TP daemon, then
we must instruct the L2TP daemon to instruct the SIU to change the Abis
Lower Transport Mode using the ALTCRQ / ALTCRP L2TP signalling.
