Kristian Nielsen 15a2b5aab1 MDEV-7940: Sporadic failure in rpl.rpl_gtid_until
Fix a race in the test case. When we do start_slave.inc immediately
followed by stop_slave.inc, it is possible to kill the IO thread while
it is still running inside get_master_version_and_clock(), and this
gives warnings in the error log that cause the test to fail.
