[PATCH] nfsd4: fix nfsd4_lock cleanup on failure
release_state_owner also puts the lock owner on the close_lru. There's no
need for that, though; replays of the failed lock would be handled by the
openowner not the lockowner.
Also consolidate the cleanup a bit, fixing leaks that can happen if errors
occur between the time a new lock owner is allocated and the lock is done.
Remove a comment and dprintk that look a little redundant.
