net: Only access network devices after init
In the efi_loader main loop we call eth_rx() occasionally. This rx function might end up calling into devices that haven't been initialized yet, potentially resulting in a lot of transfer timeouts. Instead, let's make sure the ethernet device is actually initialized before reading from or writing to it.
