Roel Kluin b9bdcd9bd7 net pcmcia: worklimit reaches -1
with while (--worklimit >= 0); worklimit reaches -1 after the loop. In
3c589_cs.c this caused a warning not to be printed.

In 3c574_cs.c contrastingly, el3_rx() treats worklimit differently:

static int el3_rx(struct net_device *dev, int worklimit)
{
	while (--worklimit >= 0) { ... }
	return worklimit;
}

el3_rx() is only called by function el3_interrupt(): twice:

static irqreturn_t el3_interrupt(int irq, void *dev_id)
{
        int work_budget = max_interrupt_work;
	while(...) {
		if (...)
			work_budget = el3_rx(dev, work_budget);
		if (...)
			work_budget = el3_rx(dev, work_budget);
		if (--work_budget < 0) {
		        ...
		        break;
		}
	}
}
The error path can occur 2 too early.
