nfsd: Don't return NFS4ERR_STALE_STATEID for NFSv4.1+
RFC5661 obsoletes NFS4ERR_STALE_STATEID in favour of NFS4ERR_BAD_STATEID. Note that because nfsd encodes the clientid boot time in the stateid, we can hit this error case in certain scenarios where the Linux client state management thread exits early, before it has finished recovering all state.
