The address should be calculated before type cast, not after.
Fixes: cc02518 ("net/netvsc: split send buffers from Tx descriptors")

This is being requested for 18.11.10 as it is fixing a reported
regression introduced in 18.11.9.
If netvsc maintainers agree and it is merged in DPDK mainline this week,
I can take it into 18.11.10, otherwise it will be for 18.11.11.
Souvik, maybe you can give tested-by tags?

Ah, already applied to next-net, Ferruh is fast.
Stephen/Long - I will assume you ack this for 18.11.10 (normally it
would be 18.11.11 after 20.11 release). Please let me know if any doubt.
