iio: Fix fwnode_handle in __fwnode_iio_channel_get_by_name()
In the fwnode_iio_channel_get_by_name(), iterating over parent nodes to
acquire IIO channels via fwnode_for_each_parent_node(). The variable
chan was mistakenly attempted on the original node instead of the
current parent node. This patch corrects the logic to ensure that
__fwnode_iio_channel_get_by_name() is called with the correct parent
node.
