In some cases, the wait_completion got interrupted. This caused the
error-handling to mutex_unlock the function. The before turned on
interrupt then got called anyway. In the ISR then completion() was
called causing wrong adc-values returned in a following adc-readout.
Reinitialise completion struct to make sure the counter is zero
when beginning a new adc-conversion.
