- 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.
