spi: omap-100k: Clean the value of 'status' is not used

An error code is set to 'status' before exiting list_for_each_entry()
loop, but the value of 'status' is not used as below:

  list_for_each_entry(t, &m->transfers, transfer_list) {
  	if (t->tx_buf == NULL && t->rx_buf == NULL && t->len) {
  		status = -EINVAL;
  		break;
  	}
  	...
  }

  status = omap1_spi100k_setup_transfer(spi, NULL);
