This patch cleans up several pieces of redundant code in the Rx clean-up paths. The first bit is that hdr_addr and the status_err_len portions of the Rx descriptor represent the same value. As such there is no point in setting them to 0 before setting them to 0. I'm dropping the second spot where we are updating the value to 0 so that we only have 1 write for this value instead of 2. The second piece is the checking for the DD bit in the packet. We only need to check for a non-zero value for the status_err_len because if the device is done with the descriptor it will have written something back and the DD is just one piece of it. In addition I have moved the reading of the Rx descriptor bits related to rx_ptype down so that they are actually below the dma_rmb() call so that we are guaranteed that we don't have any funky 64b on 32b calls causing any ordering issues.
