NFSv4: Replace closed stateids with the "invalid special stateid"
When decoding a CLOSE, replace the stateid returned by the server with the "invalid special stateid" described in RFC5661, Section 8.2.3. In nfs_set_open_stateid_locked, ignore stateids from closed state. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
