Replace xprt_create_proto/rpc_create_client with new rpc_create()
interface in the Network Lock Manager.
Note that the semantics of NLM transports is now "hard" instead of "soft"
to provide a better guarantee that lock requests will get to the server.
Test plan:
Repeated runs of Connectathon locking suite. Check network trace to ensure
NLM requests are working correctly.
