NFSD: SETCLIENTID_CONFIRM returns NFS4ERR_CLID_INUSE too often
According to RFC 3530bis, the only items SETCLIENTID_CONFIRM processing
should be concerned with is the clientid, clientid verifier, and
principal. The client's IP address is not supposed to be interesting.
And, NFS4ERR_CLID_INUSE is meant only for principal 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.
