    net: bandaid for plugging a fw_com leak in fwip_detach()
    
    Adding a temporary workaround for plugging a fw_com upon if_fwip unloading.
    
    Steps to reproduce(needs two hosts connected with firewire):
    
      while true; do
        ifconfig fwip0 10.0.0.5 up
        fwcontrol -r
        ping -c 10.0.0.3
        kldunload if_fwip
      done
    
    There's a chance that the unloading of if_fwip.ko triggers following warning:
    
            Warning: memory type fw_com leaked memory on destroy (1 allocations, 64 bytes leaked).
