netvsc: fix race during initialization
When device is being setup on boot, there is a small race where
network device callback is registered, but the netvsc_device pointer
is not set yet. This can cause a NULL ptr dereference if packet
arrives during this window.
Fixes: 46b4f7f5d1f7 ("netvsc: eliminate per-device outstanding send counter")
