Fix parallel sort, broken by the balanced merge patch. The code for initializing the tapes on each merge iteration was skipped in a parallel worker. I put the !WORKER(state) check in wrong place while rebasing the patch.
That caused failures in the index build in 'multiple-row-versions' isolation test, in multiple buildfarm members. On my laptop it was easier to reproduce by building an index on a larger table, so that you got a parallel sort more reliably.
