The commit you refer to  adds transmission of a SNDCP XID message after
successful PDP context activation.  See the unk in
sgsn_libgtp.c:send_act_pdp_cont_acc(),were the code

* assumes there is an LLME and associated LLEs
* sends SNDCP over that

I guess all that's needed is to put this into a section that is
conditional to Gb/GPRS and skip that on Iu/UMTS

As the IuPS code was not in master yet at the time the GPRS compression
was developed, this is more or less a "logical" result.
