Currently, when dealing with UDP tunnel pkts checksum offloading,
the outer-udp checksum will be offloaded by default. So the
'csum set outer-udp hw/sw' command does not work.
This patch fixes judgment of the EIPT flag and enables the
'csum set outer-udp hw/sw' command by adding judgment for the
outer-udp checksum offload flag.
Fixes: 0c550022fb82 ("net/iavf: fix Tx descriptors for IPsec")
