virsh: be consistent with style of loop exit
    
    When waiting for a block job, the various statuses (COMPLETED, READY,
    CANCELED, etc.) should all be treated consistently by having the loop be
    exited with "break". Use "goto cleanup" for the error cases only, when
    no block job status is available.
