net: hns: hisilicon: hns_dsaf_mac: switch to scoped device_for_each_child_node()

Browse Source 
Use device_for_each_child_node_scoped() to simplify the code by removing
the need for explicit calls to fwnode_handle_put() in every error path.
This approach also accounts for any error path that could be added.
