iio: trigger: Fix condition for own trigger

The condition for checking if triggers belong to the same IIO device to
set attached_own_device is currently inverted, causing
iio_trigger_using_own() to return an incorrect value. Fix it by testing
for the correct return value of iio_validate_own_trigger().
