    mlx5e: Make TLS tag zones unmanaged
    
    These zones are cache zones used to allocate TLS offload contexts from
    firmware.  Releasing items from the cache is a sleepable operation due
    to the need to await a response from the firmware command freeing the
    tag, so items cannot be reclaimed from the zone in non-sleepable
    contexts.  Since the cache size is limited by firmware limits, avoid
    this by setting UMA_ZONE_UNMANAGED to avoid reclamation by uma_timeout()
    and the low memory handler.
