libroot: Fix possible typo in printf_size.c
It appears as if there is a typo in printf_size.c; it makes
no sense to compare an unitialized variable in such a way.
Since `info->width` is referenced later on in the variable
assignment, it seems possible that the intended statement
was to place the larger of the values between `info->width`
and `info->prec` into `width`.
Fixes CID 609431.
