net: sgi: ioc3-eth: separate tx and rx ring handling
After allocation of descriptor memory is now done once in probe handling of tx ring is completely done by ioc3_clean_tx_ring. So we remove the remaining tx ring actions out of ioc3_alloc_rings and ioc3_free_rings and rename it to ioc3_[alloc|free]_rx_bufs to better describe what they are doing.
