p54pci: fix bugs in p54p_check_tx_ring
commit 0250ececdf6813457c98719e2d33b3684881fde0 upstream. Hans de Goede identified a bug in p54p_check_tx_ring: there are two ring indices. 1 => tx data and 3 => tx management. But the old code had a constant "1" and this resulted in spurious dma unmapping failures.
