commit 6165a16a5ad9b237bb3131cff4d3c601ccb8f9a3 upstream.
When we're using a cached open stateid or a delegation in order to avoid sending a CLAIM_PREVIOUS open RPC call to the server, we don't have a new open stateid to present to update_open_stateid(). Instead rely on nfs4_try_open_cached(), just as if we were doing a normal open.
