NR UE fix get_Qm_dl and nr_get_code_rate_dl

Thomas Schlichter requested to merge NR_UE_get_Qm_dl_fix into develop

Check the provided MCS index according to the specified table. Some tables go up to MCS index 27, others up to MCS index 28. If the MCS index exceeds the allowed limit, assume max. MCS.

This fixes some assertion about Qm being 0.

Now, the only remaining UE crash for me is:
