NFS: Avoid infinite loop when RELEASE_LOCKOWNER getting expired error
Fix Commit 60ea681299 (NFS: Migration support for RELEASE_LOCKOWNER)

client                            server
   RELEASE_LOCKOWNER(old clid) ----->
                <--- expired error
   RENEW(old clid)             ----->
                <--- expired error
   SETCLIENTID                 ----->
                <--- a new clid
   SETCLIENTID_CONFIRM (new clid) -->
                <--- ok
   RELEASE_LOCKOWNER(old clid) ----->
                <--- expired error
   RENEW(new clid)             ----->
                <-- ok
   RELEASE_LOCKOWNER(old clid) ----->
                <--- expired error
   RENEW(new clid)             ----->
                <-- ok
