The message is never sent to the RRC. And this message is to be
forwarded by the DU to the UE, hence it should not even be handled by
the RRC (as the RRC in the CU sends it).

The RRC container is transparent for the DU. Hence, we should not decode
it.

During the Initial UL RRC Message, the CellGroup is created. Since the
CellGroup specifies the SRB1, the SRB1 should also be created (because
the DL RRC Messages is sent via SRB1). However, before this commit, the
CellGroup is created while having the RLC lock, so we cannot create
SRB1, as it results in a deadlock.

Therefore, we now first create CellGroup, SRB0, and SRB1, before giving
the UE message to the RLC.

In case of unaligned input array, a DFT of wrong size was executed instead of a correct IDFT.
