3.16.57-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Jason Wang <[email protected]> commit 4cd879515d686849eec5f718aeac62a70b067d82 upstream. We don't stop device before reset owner, this means we could try to serve any virtqueue kick before reset dev->worker. This will result a warn since the work was pending at llist during owner resetting. Fix this by stopping device during owner reset.
