MR !1193 : Update for 5G SA implementation

When there is a retransmission, we want to use the same number of RBs.

The RBs are allocated by groups (RBGs).

In some cases (like a cell with 25 PRBs), the last RBG contains less RBs.
So in case of a retransmission, if this last RBG was used before we need
to reuse it to have the same number of RBs. If not, we will use more RBs
for the retransmission than the previous transmission.

In an experiment with two UEs (quectel modules) it was seen that when a
retransmission happens with a different number of RBs then the UE is not
happy at all, leading to way more NACKs in the harq processes than should
happen (actually the first NACK was not a NACK at all, but the eNB did
interpret it as a NACK; so the next transmission should simply be discarded
by the UE that successfully received the first transmission; instead the UE
fails to decode the data and sends a NACK, a real one this time).

Maybe it's not the correct solution, but it improve things, there are
much less NACKs.
