commit ac791f19a273a7fe254a7596f193af6534582a9f upstream.

If the tx_ignore_nack_until_eom error injection was activated,
then tx_nacked was never set instead of setting it when the last
byte of the message was transmitted.

As a result the transmit was marked as OK, when it should have
been NACKed.

Modify the condition so that it always sets tx_nacked when the
last byte of the message was transmitted.
