- changed Mdlharq to Mlimit when comparing with the round number
- Not incrementing the HARQ round in case of err_flag = 1, until HARQ is implemented
- Changed MAX_LDPC_ITERATIONS to 5 from 4 (provided better performance)

- Setting the payload to random data instead of all zeros at the Tx side

- Handling "nb_symb_sch" equal to 0 in "phy_procedures_nrUE_RX" which prevents
  entering "nr_ue_pdsch_procedures"

- Handling symbol loop problem in "nr_ue_pdsch_procedures"

- Handling resource block loop problem in "nr_rx_pdsch"

For whatever reason, ru->frame_parms was NULL and the RRU crashed.
Let's allocated memory.

Also, don't do fp = ru->frame_parms in ru_thread, it seems that it
takes the value before allocation (so: NULL) and the code crashes
later on.

Maybe it's not the correct solution. To be refined at some point.
