    libvirt: remove pointless loop after live migration finishes

    The libvirt 'migrateToURI' API(s) all block the caller until the
    live migration operation has completed. As such, the timer call
    used to check if live migration has completed is entirely pointless.
    It appears this is code left over from the very first impl of live
    migration in Nova, when Nova would simply shell out to the 'virsh'
    command instead of using the libvirt APIs. Even back then though
    it looks like it was redundant, since the command being spawned
    would also block until live migration was finished.

    Conflicts:
     nova/virt/libvirt/driver.py
