node: e2e: docs and fix for teardownSRIOVConfig

Document why teardownSRIOVPod has to wait for all the containers
to be gone before to end, and why is important.

Additionally, change the code to wait for all the containers to be gone,
not just the first. This is both a little cleaner and a little safer,
even though it seems the current code caused no issues so far.
