    Don't delete br-int to br-tun patch on startup

    When starting up, we don't want to delete the patch port between br-int
    and br-tun unless we're also dropping the flows.. In liberty both of
    these bridges were switched to not dump flows on startup and to put the
    bridges in secure mode so that default flood flows are not installed
    when the bridge is created.

    Without this patch the patch port is torn down and not reinstalled until
    br-tun is setup again.
