[PATCH v2] Documentation: iio: fix typo in triggered-buffers example

[Stepan Ionichev]

In the "IIO triggered buffer setup" example, iio_triggered_buffer_setup()
is called with "sensor_iio_polfunc" (single 'l') while the function is
defined and later referenced as "sensor_iio_pollfunc" (double 'l'). Fix
the misspelling so the example is consistent.

v2:
- Drop the file name and line numbers from the commit body, refer
  to the example by its section name instead (per Andy)
