Removed logic around CALLOCs

When we check if the pointer is NULL before CALLOCing,
then the gNB will crash. It seems that we are mostlikely
leaking memeory since the gNB only crashes with the old
change. By reverting these changes, the gNB does not crash.
We are seeing UE-to-UE IP traffic on this commit when
the tunnel interfaces are established (~50% of the time).
