nfsd4: match close replays on stateid, not open owner id
Keep around an unhashed copy of the final stateid after the last close using an openowner, and when identifying a replay, match against that stateid instead of just against the open owner id. Free it the next time the seqid is bumped or the stateowner is destroyed. Signed-off-by: J. Bruce Fields <bfields@redhat.com>
