Subject: [PATCH 2/4] usb: typec: tipd: Fix spurious fwnode_handle_put in error path

The err_role_put error path always calls fwnode_handle_put to release
the fwnode. This path can be reached after probe itself has already
released that fwnode though. Fix that by moving fwnode_handle_put in the
happy path to the very end.
