[net-next PATCH v3] tcp: Add logic to check for SYN w/ data in tcp_simple_retransmit

From: Alexander Duyck There are cases where a fastopen SYN may trigger either a ICMP_TOOBIG message in the case of IPv6 or a fragmentation request in the case of IPv4. This results in the socket stalling for a second or more as it does not respond to the message by retransmitting the SYN frame.
