a_iface: Include CSFB Indication into BSSMAP CLEAR COMMAND

When a call ends that has been established in an CSFB context, we should
add a CSFB Indication IE to the BSSMAP CLEAR COMMAND to instruct the BSC
to add further CSFB related IEs into the RR RELEASE.

- Check if an SGs association exists and add CSFB Indication IE
