net: pcnet: check rx/tx descriptor ring length
The AMD PC-Net II emulator has set of control and status(CSR) registers. Of these, CSR76 and CSR78 hold receive and transmit descriptor ring length respectively. This ring length could range from 1 to 65535. Setting ring length to zero leads to an infinite loop in pcnet_rdra_addr() or pcnet_transmit(). Add check to avoid it.
