I've finally had a look at this and unfortunately cannot find the problem. The main reason being that I cannot reproduce it. I built the same kernel and mdadm and created a very similar array and tried to grow it and it all went smoothly. In your case it didn't start the reshape at all (reshape position was zero) so something went wrong very early. If you feel like trying to reproduce it again that might be helpful. Then I would ask you to run the "mdadm --grow" command under strace -o /tmp/foo -f mdadm --grow .... and send me the /tmp/foo. But I won't be surprised if you cannot reproduce. Sad really.
