net: eth-uclass: ignore unavailable devices
device_probe() may fail in which case the seq_id will be -1. Don't display these devices during startup. While this is only a cosmetic change, the return value of eth_initialize() will also change to the actual number of available devices. The return value is only used in spl_net to decide whether there are any devices to boot from. So returning only available devices is also more correct in that case.
