Eric Dumazet ed3bc31ed0 tcp: fix races in tcp_v[46]_err() 
[ Upstream commit fde6f897f2a184546bf5516ac736523ef24dc6a7 ]

These functions have races when they:

1) Write sk->sk_err
2) call sk_error_report(sk)
3) call tcp_done(sk)

As described in prior patches in this series:

An smp_wmb() is missing.
We should call tcp_done() before sk_error_report(sk)
to have consistent tcp_poll() results on SMP hosts.

Use tcp_done_with_error() where we centralized the
correct sequence.

Fixes: 1da177e4c3 ("Linux-2.6.12-rc2")
