[PATCH 09/13] iio: addac: ad74413r: Use __free(fwnode_handle) to replace fwnode_handle_put() calls

us to exit directly from error conditions within the
fwnode_for_each_available_child_node(dev, child) loop. On normal exit
from that loop no fwnode_handle reference will be held and the child
pointer will be NULL thus making the automatically run
fwnode_handle_put() a noop.
