- according to 5.3.7.4 of TS 38.331: 1> re-establish RLC for SRB1;
- gNB:
1) re-establish RLC for SRB1 in nr_rlc_update_id
2) re-establish RLC for remaining RBs concurrently with RRCReconfiguration

issue: gNB) in nr_rlc_update_id the gNB is re-establishing RLC for all
            RBs at the same time when receiving RRCReestablishmentRequest
            from UE
        UE) according to the specs, the UE is re-establishing RLC for
            SRB1 with RRCReestablishmentRequest the other RBs are
            re-established during RRCReconfiguration (in our case in
            nr_rrc_ue_process_RadioBearerConfig) when receiving
            reestablishRLC IE in rlc_BearerToAddModList
    RLC TX) this leads to RLC counters mismatch after re-establishment:
            control PDUs discarded until max nb of retx is reached
            and then UL failure occurs
