dm: eth: Pass the packet pointer as a parameter to recv

Stop forcing drivers to call net_process_received_packet() - formerly
called NetReceive(). Now the uclass will handle calling the driver for
each packet until the driver errors or has nothing to return. The uclass
will then pass the good packets off to the network stack by calling
net_process_received_packet().
