simulator: fix off by one error in USB ack calculations
The sim's printout of the number of expected USB acks was off by one.
Since the sim queue is not registered for broadcasts, it will not
receive an ack message and does not need to account for itself when
determining the number of acks to expect, unlike the USB code.
