usb: typec: anx7411: fix fwnode_handle reference leak

commit 645d56e4cc74e953284809d096532c1955918a28 upstream.

An fwnode_handle and usb_role_switch are obtained with an incremented
refcount in anx7411_typec_port_probe(), however the refcounts are not
decremented in the error path. The fwnode_handle is also not decremented
in the .remove() function. Therefore, call fwnode_handle_put() and
usb_role_switch_put() accordingly.
