Don't just reflexively add extra debug code.

In this case pLed->LedPin is either LED_PIN_LED0 or LED_PIN_LED1.
The LED_PIN_GPIO0 and default cases are never used.  Even if it were
I think we would want to set pLed->bLedOn = true in the default
case.

The code is ugly as pants, but it works fine as is.
