We could have used that variable for an assert like
Assert(state->worker <= shared->nTapes) in worker_freeze_result_tape()
before accessing shared->tapes[state->worker] = output; as sometimes
state->worker is being set to -1. But, it seems like we reach
worker_freeze_result_tape(), only when WORKER(state) is true. So, we
don't need that extra Assert and removing nTapes variable makes sense
to me.

Patch looks good to me. Regression tests make check and make
check-world ran successfully.
