usb: typec: fix unreleased fwnode_handle in typec_port_register_altmodes()

commit 9581acb91eaf5bbe70086bbb6fca808220d358ba upstream.

The 'altmodes_node' fwnode_handle is never released after it is no
longer required, which leaks the resource.

Add the required call to fwnode_handle_put() when 'altmodes_node' is no
longer required.
