iio: adc: at91_adc: change at91_ts_sample to return void

Browse Source 
The return value of at91_ts_sample() is never checked by its caller.
Change the return type to void to make this explicit. The error
conditions are already logged via dev_err() which provides sufficient
visibility into hardware issues.
