iio: adc: Use complete() instead of complete_all() 



There is only one waiter for the completion, therefore there
is no need to use complete_all(). Let's make that clear by
using complete() instead of complete_all().

The usage pattern of the completion is:

waiter context                          waker context

nau7802_read_irq()
  reinit_completion()
  nau7802_read_conversion()
  wait_for_completion_interruptible_timeout()

                                        nau7802_eoc_trigger()
                                          complete()
