There is an off-by-one issue for the err_chained_bd path, it will free one more tx_swbd than expected. But there is no such issue for the err_map_data path. To fix this off-by-one issue and make the two error handling consistent, the increment of 'i' and 'count' remain in sync and enetc_unwind_tx_frame() is called for error handling.
