Robert Watson e0bef1cb35 Revert parts of tcp_input.c:1.255 associated with the header predicted 
cases for tcp_input():

While it is true that the pcbinfo lock provides a pseudo-reference to
inpcbs, both the inpcb and pcbinfo locks are required to free an
un-referenced inpcb.  As such, we can release the pcbinfo lock as
long as the inpcb remains locked with the confidence that it will not
be garbage-collected.  This leads to a less conservative locking
strategy that should reduce contention on the TCP pcbinfo lock.
