sgs_iface: do not use SGsAP-MO-CSFB-INDICATION for CSFB return

When the VLR/MSC receives an SGsAP-MO-CSFB-INDICATION message it sets
the RAN type back to SGs. This is wrong, the message
SGsAP-MO-CSFB-INDICATION has just an informative character. It informs
the VLR that the UE has initiated an MO CSFB call (service request).
