hv_netvsc: flag software created hash value
[ Upstream commit df9f540ca74297a84bafacfa197e9347b20beea5 ]
When the driver needs to create a hash value because it
was not done at higher level, then the hash should be marked
as a software not hardware hash.
Fixes: f72860afa2e3 ("hv_netvsc: Exclude non-TCP port numbers from vRSS hashing")
