- now the UE is passing again data to the upper layers in noS1 mode
- minor cleanups

nr-ip noS1 uplink: Uplink IP traffic successfully received at the IP TUN interface of the gNB now. Logs cleanup.

nr-ip noS1 uplink integration (testing with RFSIMULATOR only): Uplink IP packets received at the gNB and reaching at pdcp layer. Asserion error at pdcp_fifo_flush_sdus when trying to write on the nas socket
