Hi all! I've found some dead-locks, which can be easily triggered on master branch with default nbd configuration (reconnect-delay is 0), here are fixes.
01-02 fix real dead-locks 03 - hm. I'm not sure that the problem is reachable on master, I've faced it in my development branch where I move initial connect into coroutine and introduce non-blocking connect. So consider it as an intuitive fix. It just makes code a bit better.
