Sim doesn't start the proper count of workers

[db47h]

hwsim/hwsim.go

Lines 237 to 247 in ae8bccb

	size := len(ups) / workers
	if size*workers < len(ups) {
	size++
	}
	for len(ups) > 0 {
	size = min(size, len(ups))
	wc := make(chan struct{}, 1)
	cc.wc = append(cc.wc, wc)
	go worker(cc, ups[:size], wc)
	ups = ups[size:]
	}

If len(ups) is for example 9 and workers is 8, it will start only 9 / ((9/8)+1) = 4 workers.
