[PATCH] CodingStyle: proscribe do-while without braces.

[Josh Triplett <josht@linux.vnet.ibm.com>]

Sparse warns about do-while loops without braces; Linus's rationale from the
Sparse Git changelog:
> Add warning message for naked do-while
>
> Does it necessarily make sense? Dunno, but it does tend to be bad
> practice, or at least result in code that can be hard to mentally parse.
>
> Maybe that mental parsing is just me.	 Or maybe it should be warned
> about. You decide.
