NR UE: in nr_ue_scheduler.c set LCID_buffer_remain to 0 if RLC indicates not
more bytes in buffer

If the RLC indicates that there is no more data in the buffer, also the
scheduler's LCID_buffer_remain should be set to 0. Else the UE sends BSR
indicating it has data to be transmitted. The gNB would then unnecessarily
schedule UL for this UE, which would not be used, as there is no actual data
to be transmitted.
