iio: lsiio: fix error code handling error commit acf50b3586f8d8a7530b905e111dda41876d38f4 "tools:iio:lsiio: add error handling" introduced error handling of errors returned from read_sysfs_string(), but with a simple if (retval), missing the fact that these functions return a positive value if the read was successful. As a result lsiio regresses and does not show any devices on my filesystem. Fix this by checking for only negative error codes.
