Kuma Version

2.9.1

Describe the bug

Sometimes I see metadata cannot be nil when proxy disconnects. It's because watchdog is scheduled when proxy disconnects.

As an example, it occurred 4 times over last 3 days with 100s of proxies.

To Reproduce

Might be a bit hard to reproduce

Expected behavior

No such log

Additional context (optional)

We need better checks in Dataplane Watchdog that context was already cancelled
