Don't use the 'do {} while (0)' wrapper in a single statement macro.

Caught by checkpatch: "WARNING: Single statement macros should not
use a do {} while (0) loop"

Signed-off-by: Geyslan G. Bem <geyslan@gmail.com>

Change in v3:
 - There's no need to evaluate COUNT(x) in #ifdef EHCI_STATS
   false branch. Thus an empty #define is the choice.
