greatfet: don't print misleading "unknown" libusb error text

Only lookup libusb error messages for negative return values which
communicate error codes. Positive return values are transmission counts
and are not an error.

The "UNKNOWN" messages only were seen at higher log levels. Users were
not affected by the issue.
