rpl.rpl_semi_sync_ack_thread in_get_master_version_and_clock

[George Ormond Lorch III]

Test leaves DEBUG_SYNC set to in_get_master_version_and_clock

rpl.rpl_semi_sync_ack_thread 'mix' w6 [ pass ] 34478

MTR's internal check of the test case 'rpl.rpl_semi_sync_ack_thread' failed.
This means that the test case does not preserve the state that existed
before the test case was executed. Most likely the test case did not
do a proper clean-up. It could also be caused by the previous test run
by this thread, if the server wasn't restarted.
This is the diff of the states of the servers before and after the
test case was executed:
