Haiyang Zhang 7e7fefde7d hv_netvsc: Fix napi reschedule while receive completion is busy
[ Upstream commit 6b81b193b8 ]

If out ring is full temporarily and receive completion cannot go out,
we may still need to reschedule napi if certain conditions are met.
Otherwise the napi poll might be stopped forever, and cause network
disconnect.
