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)
