stress/sizes: Fix an off-by-one issue.
...
Algorithmically, a size greater than 1024 ZB could access one-past-the-end of
the sizes array. This couldn't really happen since SIZE_MAX is less than 1024
ZB on all platforms we support (and we pick the arguments to this function to be
reasonable anyways), but it's not like there's any reason *not* to fix it,
either.
