  SVN rev 208953 on 2010-06-09 16:42:42Z by rrs
  
  Fix serveral bugs all having to do with freeing an
  sctp_inpcb:
  1) Make sure not to remove the flag on the PCB until
     after the close() caller is back in control with the
     lock. Otherwise a quickly freeing assoc could kill the
     inpcb and cause a panic.
  
  2) Make sure all calls to log_closing have not released
     the locks before calling the log function, we don't
     want the logging function to crash us due to a freed
     inpcb.
  
  3) Make sure that when we get to the end, we release all
     locks (after removing them from view) and as long as
     we are NOT the inp-kill timer removing the inp, call
     the callout_drain() function so a racing timer won't
     later call in and cause a racing crash.
