aliguori f4af02ed1b fix bug in block-qcow2.c:alloc_cluster_offset() (Shahar Frank) 
During the debugging of the new revision of the zero dedup patch I
stepped on the following bug in block-qcow2.c:alloc_cluster_offset(). I
am not sure what the exact damage this bug can do, but it may be very
nasty because you way not notice it effects until you will do some
snapshot operations or similar actions that rely on the reference
counting.

The bug is easy to spot using the new "check" verb I added to the
qemu-img in one of the previous patches. I will resend the qemu-img
patch again with the new version of the zero dedup.
