    Fix reconnecting to libvirt

    The libvirt inspector may can't inspect data from libvirt on some occasions after
    libvirtd is restarted, though we have reconnecting logic. When this occurs, it will
    raise libvirt.VIR_ERR_INTERNAL_ERROR instead of libvirt.VIR_ERR_SYSTEM_ERROR in
    reconnecting logic. This results compute agent no longer reconnects to libvirt, and
    fails to inspect data any more. This patch is just updated to deal with INTERNAL_ERROR.
