Michael S. Tsirkin 4b3fd33f58 virtio_net: move tx vq operation under tx queue lock
[ Upstream commit 5a2f966d0f3fa0ef6dada7ab9eda74cacee96b8a ]

It's unsafe to operate a vq from multiple threads.
Unfortunately this is exactly what we do when invoking
clean tx poll from rx napi.
Same happens with napi-tx even without the
opportunistic cleaning from the receive interrupt: that races
with processing the vq in start_xmit.

As a fix move everything that deals with the vq to under tx lock.
