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.
