iio: adc: stm32: fix stm32h7_adc_enable error handling

Error handling in stm32h7_adc_enable routine doesn't unwind enable
sequence correctly. ADEN can only be cleared by hardware (e.g. by
writing one to ADDIS).
It's also better to clear ADRDY just after it's been set by hardware.

Fixes: 95e339b6e85d ("iio: adc: stm32: add support for STM32H7")
