NR fix harq round calculation

In 5G NR standard, there is a mapping for PDSCH and PUSCH HARQ rounds to redundancy version (rv):

HARQ round	redundancy version
0	0
1	2
2	3
3	1

Therefore, the inverse mapping table is:

redundancy version	HARQ round
0	0
1	3
2	1
3	2

This was wrongly implemented on the PDSCH receiving side, and on the PUSCH receiving side the mapping table from rounds to rv (nr_rv_round_map) was wrongly used for mapping rv to rounds.
