net: hns3: add a check for devcie's verion in hns3_tunnel_csum_bug()

Browse Source 
For the device whose version is above V3(include V3), the hardware
can do checksum offload for the non-tunnel udp packet, who has
a dest port as the IANA assigned. So add a check for devcie's verion
in hns3_tunnel_csum_bug().
