netdev-dpdk: Re-enable VXLAN/Geneve offload for Intel cards.

Browse Source 
Previously support for UDP tunneled traffic TCP traffic with UDP
checksum offloading did not work well in cases where the sending network
card didn't also support these features.

Some of the code had been written to assume that if a card supported
VXLAN/Geneve offloading, then it also supported outer UDP checksum
offloading. However, this was not the case for some Intel network cards.

A previous change disabled the VXLAN/Geneve offload flags for these
cards as a temporary fix. However, with "Userspace: Software fallback
for UDP encapsulated TCP segmentation.", the logic related to software
fallback for checksum offloading now anticipates this configuration.

The modification to the outer UDP offload flag is still required. This
feature does not work as expected in the current DPDK release.
