NFSv4: Return the delegation if the server returns NFS4ERR_OPENMODE

commit 3114ea7a24d3264c090556a2444fc6d2c06176d4 upstream.

If a setattr() fails because of an NFS4ERR_OPENMODE error, it is
probably due to us holding a read delegation. Ensure that the
recovery routines return that delegation in this case.
