Forward GPRS SUSPEND REQ from BTS to SGSN using BSSGP
As specified in 3GPP TS 03.60 Section 16.2.1 and 44.018 Section 3.4.15,
a Class B MS is sending a "RR GPRS SUSPEND REQ" via a DCCH to the BTS if
it wants to suspend GPRS services. As of
Change-Id I3c1af662c8f0d3d22da200638480f6ef05c3ed1f, OsmoBTS forwards
this via the PCU socket, so we need to pick it up and send it via BSSGP
to the SGSN.
Change-Id: I7b4beb413a6f974373a404b5a11c44d86ba695d3
Closes: OS#2249
