Lasse Dalegaard f8b0ea53dc serialqueue: correctly report EOF errors
If `klippy` loses connection to a device, the next `read()` from the
device file descriptor will result in a zero-byte result, i.e. an `EOF`.
Right now this gives a confusing error message, so this simply handles
the special case of `EOF` and outputs a better log message.
