  Log:
  - Previously when broadcasting to N number of interfaces we would run pfil
    hooks for each outgoing interface but also run pfil hooks _N times_ on the
    bridge interface. This is changed so pfil hooks are run once for the bridge
    interface (bridge0) and then only on the outgoing interfaces in the broadcast
    loop.
  
  - Simplify bridge_enqueue() by moving bridge_pfil() to the callers.
  
  - Check (inet6_pfil_hook.ph_busy_count >= 0), it may be possible to have a
    packet filter hooked for only ipv6 but we were only checking if ipv4 hooks
    were busy.
  
  - Minor optimisation for null mbuf check after bridge_pfil(), move it into the
    if-block as it couldnt possibly be null outside.
