False positive: Go x, _ := strconv.ParseUint(,, strconv.IntSize-1); int(x)

**Description of the false positive**

If I'm not mistaken and making a terribly stupid mistake here I would expect that Go's `strconv.IntSize-1` should cover the positive range of an `int`, regardless of architecture integer size. The actual value range returned by `strconv.ParseUint` in an `uint64` should be correctly castable to an `int` without ambiguities.

Currently, CodeQL scanning reports "Incorrect conversion between integer types". Am I getting this one horribly wrong?

**Code samples or links to source code**

```go
fd, err := strconv.ParseUint(fdInfoEntry.Name(), 10, strconv.IntSize-1)
if err != nil {
continue
}
taptunFd, err := unix.PidfdGetfd(pidfd, int(fd), 0)
```
