gsm48_ie.c: change bearer cap structure in outgoing CSD calls
Outgoing CSD calls were previously encoded with the
Bearer Capability 1 - Octet 4 "Structure" field set to
3 - Unstructured. Many Nokia, Sony Ericsson and Huawei devices
won't accept incoming CSD calls with these bits set.
Set them to 0 - Service data unit integrity for now, which
seems to work and make all tested devices happy.
