KDNET debugging transport library patched for XP/2003 doesn't work on ReactOS

This is possible thankfully to this GitHub project: https://github.com/MovAX0xDEAD/KDNET

How to reproduce:

1. Configure your VM with Intel E1000 network adapter
2. Download patched kdnet.dll and kdstub.dll for Intel network adapters
3. Place both files in %SystemRoot%\system32 directory
4. Add new entry to the freeldr.ini (or boot.ini in Windows case)

   /DEBUG /DEBUGPORT=NET /HOST_IP=192.168.1.100 /HOST_PORT=50000 /ENCRYPTION_KEY=make.reactos.great.again /W2003 /CPUFREQ=3000

5. Modify HOST_IP with your host machine local IP address
6. Remove /W2003 parameter in case you are testing on XP
7. Change CPUFREQ to your CPU MHz value — when doubt, you can take it from registry key HKLM\HARDWARE\DESCRIPTION\System\CentralProcessor\0 value ~MHz
8. Allow traffic on UDP port 50000 in firewall settings
9. Start WinDbg kernel debug with NET option (available since version 6.3.9600), it should have port 50000 by default, set the key to make.reactos.great.again accordingly
10. Reboot the VM and select new boot option

• Expected behavior:
  VM starts and attaches to WinDbg via network (tested with Windows XP SP3 x86)
• Observed behavior:
  System boots to debug mode, but it doesn't try to access network adapter, so it doesn't attach to WinDbg (tested with ReactOS MSVC build 0.4.15-dev-1249-g1f377076d78)
