gNB out of order in drb creation
gNB creates drb in SRB by the itti message NR_RRC_DCCH_DATA_IND=>rrc_gNB_decode_dcch()=>rrc_gNB_process_RRCReconfigurationComplete()=>nr_rrc_rlc_config_asn1_req()
but this can occur after the UE sent data on this channel/drb because the itti message is processed when rrc_gnb_task is scheduled by Linux
so, the gNB trace an error:
openair2/LAYER2/nr_rlc/nr_rlc_oai_api.c:177:mac_rlc_data_ind: fatal: no RB found (channel ID 4)
This is a bad design to rework
