net: usb: lan78xx: Use ETIMEDOUT instead of ETIME in lan78xx_stop_hw

Update lan78xx_stop_hw to return -ETIMEDOUT instead of -ETIME when
a timeout occurs. While -ETIME indicates a general timer expiration,
-ETIMEDOUT is more commonly used for signaling operation timeouts and
provides better consistency with standard error handling in the driver.

The -ETIME checks in tx_complete() and rx_complete() are unrelated to
this error handling change. In these functions, the error values are derived
from urb->status, which reflects USB transfer errors. The error value from
lan78xx_stop_hw will be exposed in the following cases:
- usb_driver::suspend
- net_device_ops::ndo_stop (potentially, though currently the return value
  is not used).
