net: mdio: remove redundant fwnode cleanup

Remove redundant fwnode cleanup in of_mdiobus_register_device()
and xpcs_plat_init_dev().

mdio_device_free() eventually calls mdio_device_release(),
which already performs fwnode_handle_put(), making the manual
cleanup unnecessary.

Combine fwnode_handle_get() with device_set_node() in
of_mdiobus_register_device() for clarity.
