Simon answers:
My idea was to make sure that the pcb is deleted outside the 
netconn_free function (since it is called from API thread also). Because 
of that, I included the assert for pcb==NULL to make sure future 
developers think of freeing the pdb before calling netconn_free (the 
name doesn't really tell that the pcb is not freed). Of course it is not 
really needed now, but I think it helps to avoid errors in the future.
