nfsd: return correct lockowner when there is a race on hash insert
alloc_init_lock_stateowner can return an already freed entry if there is a race to put openowners in the hashtable. Noticed by inspection after Jeff Layton fixed the same bug for open owners. Depending on client behavior, this one may be trickier to trigger in practice.
