[Ian Jackson <Ian.Jackson@xxxxxxxxxxxxx>]

commit f9ad69304fd52092c54fbf64b2937ebdb9980649
Author: Ian Jackson <ian.jackson@xxxxxxxxxxxxx>
Date:   Wed Oct 7 15:53:58 2009 +0100

    Call qemu_bh_delete at bdrv_aio_bh_cb.
    
    Also replave qemu_bh_cancel with qemu_bh_delete in bdrv_aio_cancel_em.
     Otherwise the bh will live forever in the bh list.
