Bug Description

compute/manager.py in _run_instance wraps the _spawn in a try/except that catches InstanceNotFound which can be raised after the network is allocated, but does not deallocate the network

    Deallocate network if instance is deleted in spawn

    If the instance is deleted while the virt driver is spawning, an
    InstanceNotFound exception is raised and caught in compute to prevent it
    from being rescheduled. This also deallocates the network to prevent
    leaking interfaces/mac/ips.

    * Fixes LP1068716
