The current timeout logic for Control Queue-Pair (CQP) OPs does not take into account whether CQP makes progress but rather blindly waits for a large timeout value, 100000 jiffies for the completion event. Improve this by setting the timeout based on whether the CQP is making progress or not. If the CQP is hung, the timeout will happen sooner, in 5000 jiffies. Each time the CQP progress is detetcted, the timeout extends by 5000 jiffies.
