hv_netvsc: flag software created hash value

Browse source 
[ Upstream commit df9f540ca7 ]

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: f72860afa2 ("hv_netvsc: Exclude non-TCP port numbers from vRSS hashing")
