Switch to contigmalloc in the Hyper-V code

In the Hyper-V drivers we need to allocate buffers shared between the
host and guest. This memory has been allocated with bus_dma, however
it doesn't use this correctly, e.g. it is missing calls to
bus_dmamap_sync. Along with this on arm64 we need this memory to be
mapped with the correct memory type that bus_dma may not use.

Switch to contigmalloc to allocate this memory as this will correctly
allocate cacheable memory.

Hyper-V: hn: Enable vSwitch RSC support in hn netvsc driver

Receive Segment Coalescing (RSC) in the vSwitch is a feature available in
Windows Server 2019 hosts and later. It reduces the per packet processing
overhead by coalescing multiple TCP segments when possible. This happens
mostly when TCP traffics are among different guests on same host.
This patch adds netvsc driver support for this feature.

The patch also updates NVS version to 6.1 as needed for RSC
enablement.

hyperv/hn: Fixat RNDIS rxfilter after the successful RNDIS init.

Under certain conditions on certain versions of Hyper-V, the RNDIS
rxfilter is _not_ zero on the hypervisor side after the successful
RNDIS initialization, which breaks the assumption of any following
code (well, it breaks the RNDIS API contract actually). Clear the
RNDIS rxfilter explicitly, drain packets sneaking through, and drain
the interrupt taskqueues scheduled due to the stealth packets.
