cxl/port: Keep port->uport valid for the entire life of a port
The upcoming region provisioning implementation has a need to
dereference port->uport during the port unregister flow. Specifically,
endpoint decoders need to be able to lookup their corresponding memdev
via port->uport.
The existing ->dead flag was added for cases where the core was
committed to tearing down the port, but needed to drop locks before
calling device_unregister(). Reuse that flag to indicate to
delete_endpoint() that it has no "release action" work to do as
unregister_port() will handle it.
