hotfix: replacing msg with printf in unitary simulators (msg(...) was replaced with LOG_D(PHY,...) but it was used before log was initialized)

- 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.

1. NR RU was using wrong config file descriptor. It should be the same as for the LTE RU and we should remove the NR RU config file descriptor (todo)
2. NR RU was calling feptx_prec from LTE RU procedures, which it should not. In the older versions this function didn't do anything anyway as there was a check on num_eNB, which is 0 for gNB. Now NR RU is not calling this function at all, but we have to write such a function for NR RU (todo)
