I don't understand how that has anything to do with doing the call
in either nfs4_free_stid or it's two caller.  For the open and lock
stateids nothing changes in either case, and for delegations we
move from destroy_(revoked_)delegation to the final put in
nfs4_put_delegation for both variants.  While I'd normally prefer
what you do in the patch it just seems like churn with the further
changes.
