hyperv: Fix the NETIF_F_SG flag setting in netvsc

[ Upstream commit f45708209dc445bac0844f6ce86e315a2ffe8a29 ]

SG mode is not currently supported by netvsc, so remove this flag for now.
Otherwise, it will be unconditionally enabled by commit ec5f0615642
    "Kill link between CSUM and SG features"
Previously, the SG feature is disabled because CSUM is not set here.
