  Log:
  A small race existed where the lock was dropped between when encif was
  tested and then set. [1]
  
  Reorganise things to eliminate this, we now ensure that enc0 can not be
  destroyed which as the benefit of no longer needing to lock in
  ipsec_filter and ipsec_bpf. The cloner will create one interface during the
  init so we can guarantee that encif will be valid before any SPD entries are
  added to ipsec.
