iio: adc: rzg2l_adc: add missing fwnode_handle_put() in rzg2l_adc_parse_properties()

BugLink: https://bugs.launchpad.net/bugs/1986718
commit d836715f588ea15f905f607c27bc693587058db4 upstream.

fwnode_handle_put() should be used when terminating
device_for_each_child_node() iteration with break or return to prevent
stale device node references from being left behind.
