[USS] Sync's LevelDB can get stuck when we crash and does not recover

Project Member Reported by s...@chromium.org, Aug 4 2016 
1. Repro  crbug.com/634388 
2. Relaunch chrome with --sync-enable-uss-device-info flag again
3. Maybe it'll repro and crash now?

I was only able to get into this state once, but once there I was able to hit it 2 out of 2 times when restarting chrome. Afterwards I removed Sync's LevelDB folder via

rm -rf ~/.config/chromium/Default/Sync\ Data/LevelDB/

and the problem went away. Looking back at the stack trace, I'm not quite sure what's going on.

The crash looked like:

skym@skym:~/chromiumSource/linux/src$ rd --sync-enable-uss-device-info
