Robert Watson 1e8f5ffa35 In tcp_ctloutput(), don't hold the inpcb lock over sooptcopyin(), rather, 
drop the lock and then re-acquire it, revalidating TCP connection state
assumptions when we do so.  This avoids a potential lock order reversal
(and potential deadlock, although none have been reported) due to the
inpcb lock being held over a page fault.
