Andre Puschmann 091877fd2a 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.
