Subject: [PATCH] usb: typec: ucsi: Correct teardown ordering in ucsi_init()
 error path

The commit 7aa7d4bf9d3f ("usb: typec: ucsi: Fix race condition and
ordering in port unregistration") consolidated port teardown into the
ucsi_unregister_port() helper. However, it introduced an ordering problem
in the ucsi_init() error path.

Fix this by ensuring ucsi_unregister_port() is called before we unregister
their corresponding lockdep keys.
