Michael S. Tsirkin 22bc63c58e virtio_net: move txq wakeups under tx q lock 
We currently check num_free outside tx q lock
which is unsafe: new packets can arrive meanwhile
and there won't be space in the queue.
Thus a spurious queue wakeup causing overhead
and even packet drops.

Move the check under the lock to fix that.
