The two function call API for creating a new RPC client is now obsolete.
Remove it.
Also, remove an unnecessary check to see whether the caller is capable of
using privileged network services. The kernel RPC client always uses a
privileged ephemeral port by default; callers are responsible for checking
the authority of users to make use of any RPC service, or for specifying
that a nonprivileged port is acceptable.
Test plan:
Repeated runs of Connectathon locking suite. Check network trace to ensure
correctness of NLM requests and replies.
