hyperv/hn: Workaround erroneous hash type observed on WS2016.

Background:
- UDP 4-tuple hash type is unconditionally enabled in Hyper-V on WS2016,
which is _not_ affected by NDIS_OBJTYPE_RSS_PARAMS.
- Non-fragment UDP/IPv4 datagrams' hash type is delivered to VM as
TCP_IPV4.

Currently this erroneous behavior only applies to WS2016/Windows10.

Force l3/l4 protocol check, if the RXed packet's hash type is TCP_IPV4,
and the Hyper-V is running on WS2016/Windows10. If the RXed packet is
UDP datagram, adjust mbuf hash type to UDP_IPV4.

hyperv/hn: Apply VF's RSS setting

Since in Azure SYN and SYN|ACK go through the synthetic parts while the
rest of the same TCP flow goes through the VF, apply VF's RSS settings
to synthetic parts to have a consistent hash value/type for the same TCP
flow.
