irqchip/gicv3: Handle loop timeout proper

Browse source 
The timeout loop terminates when the loop count is zero, but the decrement
of the count variable is post check. So count is -1 when we check for the
timeout and therefor the error message is supressed.

Change it to predecrement, so the error message is emitted.
