Thanks for catching that.
I think it would be simpler to pull this check out into nfsd4_open(),
something like:
case NFS4_OPEN_CLAIM_PREVIOUS:
open->op_openowner->oo_flags |= NFS4_OO_CONFIRMED;
status = nfs4_check_open_reclaim(&open->op_clientid);
if (status)
goto out;
case NFS4_OPEN_CLAIM_FH:
...
--b.

Opening file with filehandle, check reclaim is not needed.
So, let open reclaim check at nfsd4_open.
