    netif: fix removing ext-callback while callback is called
    
    When a registered netif ext-callback unregisters itself when being
    called (e.g. because some state is reached by this event), the invoke
    iteration might access uninitialized memory or at least stop the
    iteration (because next is set to null).
    
    Fix his by caching the next pointer during iteration before calling
    callbacks.
