Small tidyup for commitd41a178.
A comment was left behind claiming that we needed to use malloc() ratherthan palloc() because the corresponding free would run in anotherthread, but that's not true anymore. Remove that comment. And, withthe reason being gone, we might as well actually use palloc().Back-patch to supported releases, liked41a178.Discussion:https://postgr.es/m/CA%2BhUKG%2BpdM9v3Jv4tc2BFx2jh_daY3uzUyAGBhtDkotEQDNPYw%40mail.gmail.com
