According to RFC 3530bis, the only items SETCLIENTID_CONFIRM
processing should be concerned with is the clientid, clientid
verifier, and authentication flavor. The client's IP address
is not supposed to be interesting.
And, NFS4ERR_CLID_INUSE is meant only for authentication flavor
mismatches.
I triggered this logic with a prototype UCS client -- one that
uses the same nfs_client_id4 string for all servers. The client
mounted our server via its IPv4, then via its IPv6 address.
