Bug #5332
closedMissing BVCI in FLUSH_LL_ACK can cause segfault

Spec Reference:
Description
The BVCI IE is listed as conditional and is only included if the flush action indicates that LLC-PDUs are transferred. (3GPP TS 48.018 Ch. 10.4.2).
The code in gbprox_rx_sig_from_bss unconditionally tries to get a BVCI from a FLUSH_LL message which could result in a segfault if no such IE is included.

I believe this does what it's supposed to do, but the TTCN3 test still fails with:
Misc_Helpers.ttcn:15 setverdict(fail): none -> fail reason: ""BSSGP_Emulation.ttcnpp:820 : Couldn't find Component for TLLI 'C2180023'O"", new component reason: ""BSSGP_Emulation.ttcnpp:820 : Couldn't find Component for TLLI 'C2180023'O""
