Fix a bug which could lead to receive side lockup when WC is disabled. When submitting rx buffers and not using WC fifo, always replace the invalid DMA address with the real one, otherwise allocation failures could lead to the invalid DMA address being given to the NIC, and that would cause the receive side to lockup.
