Subject: [PATCH net-next v2 0/2] hv_netvsc: fix a hang on channel/mtu changes

It was found that netvsc driver doesn't survive e.g.

# while true; do ethtool -L eth0 combined 4; ethtool -L eth0 combined 8; done"

test. I was able to identify a hang in guest/host communication, it is
fixed by PATCH1 of this series. PATCH2 is a cosmetic change masking
unneeded messages.

Changes since v1:
- Throw away patches 2 and 3 of the original series as one is unneeded and
  the other is not justified [Eric Dumazet, Stephen Hemminger] so I'm only
  fixing the hang now, the crash doesn't reproduce. Will keep an eye on it.

  hv_netvsc: hide warnings about uninitialized/missing rndis device
