Christophe JAILLET e0a2e37f30 iio: adc: men_z188_adc: Fix a resource leak in an error handling path
If iio_device_register() fails, a previous ioremap() is left unbalanced.

Update the error handling path and add the missing iounmap() call, as
already done in the remove function.

Fixes: 74aeac4da66f ("iio: adc: Add MEN 16z188 ADC driver")
