    Change ip_lib decorators order

    Change the execution order of:
    - @privileged.default.entrypoint
    - @lockutils.synchronized("privileged-ip-lib")

    "synchronized" decorator holds the execution of the function until
    the lock is released. Using the current decorator ordering, this
    active wait is done inside the privsep context. This can exhaust
    the number of execution threads reserved for the privsep daemon.
