Eric Dumazet 07e100f984 tcp: restore fastopen with no data in SYN packet 
Yuchung tracked a regression caused by commit 57be5bdad7 ("ip: convert
tcp_sendmsg() to iov_iter primitives") for TCP Fast Open.

Some Fast Open users do not actually add any data in the SYN packet.

Fixes: 57be5bdad7 ("ip: convert tcp_sendmsg() to iov_iter primitives")
