Description
It's possible that the reference to the object request dropped
inside the loop in rbd_img_request_submit() will be the last
one, in which case the content of the object pointer can't be
trusted.
Use a safe form of the object request list traversal to avoid
problems.

- Backport set to Yes?
I don't know how to fill in the "Backport" field. But this
may be a bug we should send to Linus for the current
cycle (3.9-rc7 is scheduled this weekend I think).
