NFSv4: Update list of irrecoverable errors on DELEGRETURN
commit c97cf606e43b85a6cf158b810375dd77312024db upstream. If the DELEGRETURN errors out with something like NFS4ERR_BAD_STATEID then there is no recovery possible. Just quit without returning an error. Also, note that the client must not assume that the NFSv4 lease has been renewed when it sees an error on DELEGRETURN.
