hv_netvsc: Check status in SEND_RNDIS_PKT completion message

Browse source

[ Upstream commit dca5161f9b ]

Completion responses to SEND_RNDIS_PKT messages are currently processed
regardless of the status in the response, so that resources associated
with the request are freed.  While this is appropriate, code bugs that
cause sending a malformed message, or errors on the Hyper-V host, go
undetected. Fix this by checking the status and outputting a rate-limited
message if there is an error.
