[ Upstream commit 6165a16a5ad9b237bb3131cff4d3c601ccb8f9a3 ]
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.
Fixes: d2bfda2e7aa0 ("NFSv4: don't reprocess cached open CLAIM_PREVIOUS")
