gbproxy: Fixed RAI patching in Attach Request messages
Currently the RAI in the LLC part of the message is not updated if the message has been taken from the list of stored messages. The reason is, that old_raid_matches is update in gbprox_process_bssgp_ul() but not in gbproxy_flush_stored_messages(). This patch moves the check to gprs_gb_parse_bssgp() which is called at both places and where other fields like parse_ctx->tlli are set, too. In addition, old_raid_matches is replaced by old_raid_is_foreign since this is clearer in the case when there is no old RAI at all. Several RAI patch counter assertions are also added to test_gbproxy_ra_patching(). Sponsored-by: On-Waves ehf
