s390/qeth: remove QETH_QDIO_BUF_HANDLED_DELAYED state
Reuse the QETH_QDIO_BUF_EMPTY state to indicate that a TX buffer has been completed with a QAOB notification, and may be cleaned up by qeth_cleanup_handled_pending(). Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
