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.
