gnb,rrc: inverse order of configuring lower layers when establishing bearer
...
start with lower layers first, so MAC, RLC then PDCP.
Since PDCP requires that the LCID is already registered at RLC to make config
checks. It checks for RLC mode (UM) in this case causing log entries like:
2021-12-01T13:47:40.453641 [RLC-NR ] [W] LCID 4 doesn't exist.
