From: Cong Wang <cong.wang@xxxxxxxxxxxxx>
Currently only unix stream socket sets TCP_ESTABLISHED,
datagram socket can set this too when they connect to its
peer socket. At least __ip4_datagram_connect() does the same.
This will be used by the next patch to determine whether an
AF_UNIX datagram socket can be redirected in sockmap.
