RFC: fix a check in stat_cache_add()

[Ralph Böhme]

Hi!

I just stumbled upon a check in stat_cache_add() that seems to be wrong, cf the
commit message in the attached patch. What do you think?

Subject: [PATCH] s3: smbd: fix a check in stat_cache_add()

As the comment above the if condition says:

        /*
         * If we are in case insentive mode, we don't need to
         * store names that need no translation - else, it
         * would be a waste.
         */

Ie if stat_cache_add() is called as

        stat_cache_add("foo/bar", "foo/bar", false)

There's no need to cache the path, as a simple stat() on the client
supplied name (full_orig_name) matches the name used in the
filesystem (passed to stat_cache_add() as translated_path).

So fix the if condition to match the comment.
