gprs_gmm: send Service Reject when no PDP ctxs are available.
Look at PDP Context Status IE: if there are any PDP contexts which are
ACTIVE on MS side and there are no PDP contexts which are ACTIVE on the
network side, then send Service Reject with the cause "NO PDP
ACTIVATED". This forces MS to reactivate the PDP contexts.
3GPP TS 24.008 Section 4.7.13.4 Service request procedure not accepted
by the network. Cause # 40.
Fixes: OS#3937
