Bug description:
  [Impact]

  When using iptables rules affecting bridge traffic, and if affected
  traffic is flowing through bridge while br_netfilter module is loaded
  or unloaded, a kernel panic may occur.

  [Test Case]

  It's difficult to reproduce because of a very small race condition
  window during br_netfilter load/unload when the module is receiving
  traffic but has not yet registered its hooks (or, has unregistered its
  hooks but still has traffic it's processing).  A system must be set up
  using a bridge, and iptable netfilter rules must be set up to process
  the bridge traffic.  Then the system should be rebooted until the
  problem occurs, or the br_netfilter module should be loaded/unloaded
  until the problem occurs.

  [Regression Potential]

  Changing how the br_netfilter module switches its fake dst for a real
  dst may, if done incorrectly, result in more kernel panics if other
  code tries to process the br_netfilter module's fake dst.

  [Other Info]

  The br_netfilter module processes packets traveling through its
  bridge, and while processing each skb it places a special fake dst
  onto the skb.  When the skb leaves the bridge, it removes the fake dst
  and places a real dst onto it.  However, it uses a hook to do this,
  and when the br_netfilter module is unloading it unregisters that
  hook.  Any skbs that are currently being processed in the bridge by
  the br_netfilter module, but that leave the bridge after the hook is
  unregistered (or, during br_netfilter module load, before the hook is
  registered) will still have the fake dst; when other code then tries
  to process that dst, it causes a kernel panic because the dst is
  invalid.
