xdp-synproxy: drop IP don't fragment check

Browse Source 
When XDP DDoS syncookie program is attached
to red0 interface, green network client internet
connection to website like gmail/youtube... failed.
it is because these sites does not have IP DF flag
set for each tcp packet, and syncookie_xdp program
would drop these packets when they arrived at red0
interface.
