iio: adxl372: fix iio_triggered_buffer_{pre,post}enable positions

Browse Source 
The iio_triggered_buffer_{predisable,postenable} functions attach/detach
the poll functions.

For the predisable hook, the disable code should occur before detaching
the poll func, and for the postenable hook, the poll func should be
attached before the enable code.
