Fixes #670

There was a mistake in #595 that made worker upgrading cordon all the workers before an upgrade. The intention was to cordon only the current batch, so that workloads don't migrate to the nodes in the same batch.

I used k0sctl v0.17.8 and I confirmed that all workers cordoned before upgrading.

Why does you create another BatchedParallelEach? @kke

Yes I don't see any reason why it couldn't be in the existing one looking at it now with fresh eyes.
