hv_netvsc: Fix hash key value reset after other ops
Changing mtu, channels, or buffer sizes ops call to netvsc_attach(), rndis_set_subchannel(), which always reset the hash key to default value. That will override hash key changed previously. This patch fixes the problem by save the hash key, then restore it when we re- add the netvsc device.
