iio: adc128s052: Fix the error handling path of 'adc128_probe()'
commit bbcf40816b547b3c37af49168950491d20d81ce1 upstream. A successful 'regulator_enable()' call should be balanced by a corresponding 'regulator_disable()' call in the error handling path of the probe, as already done in the remove function. Update the error handling path accordingly.
