[PATCH net-next v1 04/21] net: usb: lan78xx: Improve error reporting with %pe specifier

[Oleksij Rempel]

Replace integer error codes with the `%pe` format specifier in register
read and write error messages. This change provides human-readable error
strings, making logs more informative and debugging easier.
