[U-Boot] [PATCHv6 17/28] fdt: fixup_eth: improve error catching/reduce identation

[Olliver Schinagl]

Currently when checking for an error in ethernet aliases in the fdt, we
only check for the error case -1. It is safer to ignore anything < 0.

By rearranging logic a bit we can now also reduce identation.
