Ensure gatherstate->nextreader is properly initialized. The previously code worked OK as long as a Gather node was never rescanned, or if it was rescanned, as long as it got at least as many workers on rescan as it had originally. But if the number of workers ever decreased on a rescan, then it could crash.
