On linux we madvise hugepages for large malloc allocations but fail to do so also for calloc allocations even though it makes just as much sense there. This aligns the two code paths.

This aligns the two (or rather three) code paths.
Closes gh-27483
I have run the test from the issue on a linux machine, and see a clear drop for the first write into the huge array (going down to be same as empty in this case, which I didn't even quite expect).
