The API to prepare checksum offloads employs outer
IP checksum flag to tell regular IPv4 packets from
tunnel packets with outer IPv4 encapsulation. This
flag cannot serve as a marker for the said purpose
because a packet can have outer IPv4 encapsulation
and may not have outer IP checksum offload request.
Fix the API by changing the said criterion to test
outer IPv4 flag rather than outer IP checksum flag.
Use simpler spelling of the conditional expression.
