nfsd4: cleanup handling of nfsv4.0 closed stateid's
Closed stateid's are kept around a little while to handle close replays in the 4.0 case. So we stash them in the last-used stateid in the oo_last_closed_stateid field of the open owner. We can free that in encode_seqid_op_tail once the seqid on the open owner is next incremented. But we don't want to do that on the close itself; so we set NFS4_OO_PURGE_CLOSE flag set on the open owner, skip freeing it the first time through encode_seqid_op_tail, then when we see that flag set next time we free it. This is unnecessarily baroque. Instead, just move the logic that increments the seqid out of the xdr code and into the operation code itself. The justification given for the current placement is that we need to wait till the last minute to be sure we know whether the status is a sequence-id-mutating error or not, but examination of the code shows that can't actually happen.
