NFSD: Fix a null reference case in find_or_create_lock_stateid()
commit d19fb70dd68c4e960e2ac09b0b9c79dfdeefa726 upstream.
nfsd assigns the nfs4_free_lock_stateid to .sc_free in init_lock_stateid().
If nfsd doesn't go through init_lock_stateid() and put stateid at end,
there is a NULL reference to .sc_free when calling nfs4_put_stid(ns).
This patch let the nfs4_stid.sc_free assignment to nfs4_alloc_stid().
Fixes: 356a95ece7aa "nfsd: clean up races in lock stateid searching..."
