  Log:
  re_detach() fixes:
  
  - Fixed if_free() logic screw-up that can either result
    in freeing a NULL pointer or leaking "struct ifnet".
  - Move if_free() after re_stop(); the latter accesses
    "struct ifnet".  This bug was masked by a previous bug.
  - Restore the fix for a panic on detach caused by racing
    with BPF detach code by Bill by moving ether_ifdetach()
    after re_stop() and resetting IFF_UP; this got screwed
    up in revs. 1.30 and 1.36.
