ALSA: hda: intel-sdw-acpi: fix usage of device_get_named_child_node()

The documentation for device_get_named_child_node() mentions this
important point:

"
The caller is responsible for calling fwnode_handle_put() on the
returned fwnode pointer.
"

Add fwnode_handle_put() to avoid a leaked reference.
