remove: Continue on "not found" errors
remove: Continue on "not found" errors

Some CNIs might return a "not found" error when removing an Endpoint / path,
which means that it was already removed. We can continue in this case; this
will mean that containerd will be able to forcefully remove Pods in this state.
