net: usb: lan78xx: Improve error handling in lan78xx_phy_wait_not_busy

Browse source

Update `lan78xx_phy_wait_not_busy` to forward errors from
`lan78xx_read_reg` instead of overwriting them with `-EIO`. Replace
`-EIO` with `-ETIMEDOUT` for timeout cases, providing more specific and
appropriate error codes.
