  Ok, _really_ fix the Intel 2100B Centrino deadlock problems this time.
  (I hope.)
  My original instinct to make ndis_return_packet() asynchronous was correct.
  Making ndis_rxeof() submit packets to the stack asynchronously fixes
  one recursive spinlock acquisition, but it's also possible for it to
  happen via the ndis_txeof() path too. So:
  - In if_ndis.c, revert ndis_rxeof() to its old behavior (and don't bother
    putting ndis_rxeof_serial() back since we don't need it anymore).
  - In kern_ndis.c, make ndis_return_packet() submit the call to the
    MiniportReturnPacket() function to the "ndis swi" thread so that
    it always happens in another context no matter who calls it.
