iio: adc: aspeed: Fix refcount leak in aspeed_adc_set_trim_data
of_find_node_by_name() returns a node pointer with refcount incremented, we should use of_node_put() on it when done. Add missing of_node_put() to avoid refcount leak. Fixes: d0a4c17b4073 ("iio: adc: aspeed: Get and set trimming data.")
