Two missing braces, one close and one open, fabulously let the code
compile.

The *really* amazing thing about this (at least as far as I can see) is
the missing braces didn't alter the semantics of the code, except that
with the patch we no longer generate an extra TCG op with no effect...

I'm surprised checkpatch didn't insist you added braces to the "if"
half of this if-else as well.
thanks

I must admit I ignored it. It makes the patch harder to review, since
the bug is explicitly about missing (unmatched) braces. I can add the
braces throughout the file, but I don't think it's a reason to obfuscate
this particular patch.
