Hanna Reitz dc70638ff6 block/qed: Keep auto_backing_file if possible 
Just like qcow2, qed invokes its open function in its
.bdrv_co_invalidate_cache() implementation.  Therefore, just like done
for qcow2 in HEAD^, update auto_backing_file only if the backing file
string in the image header differs from the one we have read before.
