MR921 : Hotfix for DL DCI issue in UE  
Fixing a bug from last MR.  
Fix in nr_dlsim that prevents reporting false 'PDSCH ok' message

MR915 : Fix to avoid RRC->X2AP ticking every msec when x2ap task is not enabled  
The aim of itti RRC_SUBFRAME_PROCESS message (MAC->RRC) is to trigger an itti X2AP_SUBFRAME_PROCESS message (RRC->X2AP)  
This change avoids creating RRC_SUBFRAME_PROCESS message if x2ap task is not enabled

UE initiates the RA procedure with sending message 1 via PRACH 150 frames after synchronizing with the gNB.
As the frame numbers wrap at 1024, we have to calculate the frame number for message 1 using modulo calculation.

The T tracer macpdu2wireshark has been modified to handle the new traces.
The usage is the same as for LTE.

In NR the RACH is logged as an LTE RACH. Maybe we'll change that in the
future. Looking at the source code of wireshark, I could not find any
way to report NR RACH. Maybe they forgot it. Or I did not search correctly...
