hv_netvsc: Allow scatter-gather feature to be tunable
In a previous patch, the NETIF_F_SG was missing after the code changes.
That caused the SG feature to be "fixed". This patch includes it into
hw_features, so it is tunable again.
Fixes: 23312a3be999 ("netvsc: negotiate checksum and segmentation parameters")
