Bug description:
  [Impact]

   * Virsh can't merge snapshots using the Block Commit technique
   * It is only possible to merge base to top image (not the opposite)
   * Combination of libvirt v1.2.2 and QEMU 2 is no good for Block Commit
   * After this fix, virsh won't hang on the opration, will cause an error

  [Test Case]

   * Workaround in Commit #10
   * QEMU is fine in Commit #11
   * Test Case in Commit #12

  [Regression Potential]

   * Block commit (Already broken) would continue not working
   * Its a small fix based on upstream fix (to block this function)

  [Other Info]
   
  ## Original Case Description

  virsh blockcommit hangs at 100% and nothing happens.
