Fix "Received Nack" log for Msg4/MsgB and minor improvement in RA logs

Fix "Received Nack" log for Msg4/MsgB, in 4-Step RA. When there is a Msg4 NACK,
we have this log:

[NR_MAC]   (UE 91db) Received Nack in MsgB, preparing retransmission!

This MR fixes the message and now works correctly both in 4-Step RA and 2-Step RA.
Other additional but minor improvement in RA logs.
