g115: incorrect check.

[kehiy]

Summary

Steps to reproduce the behavior

use this code:

kind, err := strconv.ParseUint("<number>", 10, 16)
if err != nil {
    return err
}

v := uint16(kind)

in this case, based on golang document i would get an error when the number is more than uint16 bisize and this is handled. but i still get a g115 error.
