gianfar: Don't needlessly set the wrap bit for the last RX BD
startup_gfar() sets the wrap bit for the last rxbd just after gfar_new_rxbdp() call, which is issued for all rxbds. And gfar_new_rxbdp() has the following check already: if (bdp == priv->rx_bd_base + priv->rx_ring_size - 1) lstatus |= BD_LFLAG(RXBD_WRAP); So we don't need to set the bit again.
