libceph: reset connection retry on successfully negotiation
We exponentially back off when we encounter connection errors. If several errors accumulate, we will eventually wait ages before even trying to reconnect. Fix this by resetting the backoff counter after a successful negotiation/ connection with the remote node. Fixes ceph issue #2802.
