[PATCH v4 12/15] iio: addac: ad74413r: Use device_for_each_child_node_scoped()

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Switching to the _scoped() version removes the need for manual
calling of fwnode_handle_put() in the paths where the code
exits the loop early. In this case that's all in error paths.

The use of fwnode_for_each_available_child_node() here is assumed
to have been down to a false assumption that device_for_each_child_node()
doesn't check avaialble - so this transition to the scoped
device_for_each_child_node_scoped() is equivalent.
