iio: adc: Fix incorrect exit of for-loop
commit 5afc1540f13804a31bb704b763308e17688369c5 upstream.
Currently the for-loop that scans for the optimial adc_period iterates
through all the possible adc_period levels because the exit logic in
the loop is inverted. I believe the comparison should be swapped and
the continue replaced with a break to exit the loop at the correct
point.
Addresses-Coverity: ("Continue has no effect")
Fixes: e08e19c331fb ("iio:adc: add iio driver for Palmas (twl6035/7) gpadc")
