Subject: [PATCH] iio: Fix return value check for set_trigger_state()

In `iio_trigger_detach_poll_func()` the return value from
`trig->ops->set_trigger_state(trig, false)` is checked with `if (ret)`.
However, in `iio_trigger_attach_poll_func()` it is checked with
`if (ret < 0)`. Fix this mismatch by only checking for `if (ret)` in
both places.
