os: remove duplicate check from windows os.Stat

[markus-oberhumer]

There is a duplicate check for file == nil in the windows version of os.Stat().

Seems like an oversight in git commit 11c7b44 by @ianlancetaylor .

What version of Go are you using (go version)?

Current go git master 1.9.x 73d0273 .

What did you do?

$ git diff 73d02735734e1ed1e4d1f5a7c534206596f3903a
diff --git a/src/os/stat_windows.go b/src/os/stat_windows.go

                // I don't know any better way to do that for directory
                return Stat(file.dirinfo.path)

Please feel free to fix this trivial issue by yourself - I don't have a Gerrit account and a CLA (yet).
