    kernel - Fix lockmgr lock mismatch panics when iwn used without wlan
    
    * If if_iwn is ifconfig'd without going through wlan the wlan_serializer
      is not held during the firmware load stage, resulting in a panic.
      Acquire the serializer for this case.
    
    * Note: iwn worked fine with wlan, but this fixes an annoying panic when
      people try to mess with it without wlan.
