Description:
If a transaction was aborted during node-failure handling
it could rarely "forget" to return a commit ack marker,
this left the commit ack marker in a inconsistent state
which could lead to api-failure handling later not completing

How to repeat:
testNodeRestart -n NR_Hammer -r 5 T1
(new testcase)

Suggested fix:

Documented fix in the NDB-6.2.17 and NDB-6.3.20 changelogs as follows:

        If a transaction was aborted during the handling of a data node
        failure, this could lead to the later handling of an API node
        failure not being completed.
