iio: adc: stm32-adc: Fix of_node_put() issue in stm32-adc
Fix following coccicheck warning:
./drivers/iio/adc/stm32-adc.c:2014:1-33: WARNING: Function
for_each_available_child_of_node should have of_node_put() before return.
Early exits from for_each_available_child_of_node should decrement the
node reference counter. Replace return by goto here.
