rbd: fix an incorrect assertion condition
In rbd_img_obj_parent_read_full_callback() there is an assertion intended to verify the size of the image request for a full parent read was the size of the original request's target object. But assertion was looking at the parent image order rather than the original one, and these values can differ. Fix that.
