- Consolidate the code that free's chunks to actually also

  call the sctp_free_remote_address() function.
- Assure that when we allocate a chunk the whoTo is NULL,
  also when we free it and place it into the cache we NULL
  it (that way the consolidation code will always work).
- Fix a small race, when a empty data holder is left on the stream
  out queue, and both sides do a shutdown, the empty data holder
  would prevent us from sending a SHUTDOWN-ACK and at the same time we
  never  would cleanup the empty holder (since nothing was ever in queue).
  We now add a utility function that a) cleans up empty holders and
  b) properly determines if there are still pending data chunks on
  the stream out wheel.
