Eric Dumazet 0a8de364ff tcp: no longer abort SYN_SENT when receiving some ICMP 
Currently, non fatal ICMP messages received on behalf
of SYN_SENT sockets do call tcp_ld_RTO_revert()
to implement RFC 6069, but immediately call tcp_done(),
thus aborting the connect() attempt.

This violates RFC 1122 following requirement:

4.2.3.9  ICMP Messages
...
          o    Destination Unreachable -- codes 0, 1, 5

                 Since these Unreachable messages indicate soft error
                 conditions, TCP MUST NOT abort the connection, and it
                 SHOULD make the information available to the
                 application.

This patch makes sure non 'fatal' ICMP[v6] messages do not
abort the connection attempt.

It enables RFC 6069 for SYN_SENT sockets as a result.
