Currently, we enable the receiver before setting the ring address which could
lead the card DMA into unexpected areas. Solving this by set the ring address
before enabling the receiver.

btw. I find and test this in qemu as I didn't have a 8139cp card in hand. please
review it carefully.

I hate bugs like this, the other common issue is enabling interrupts
before the chip is fully programmed.

Applied, thanks.
