 Description   

galera_sr.GCF-1060 sometimes produces wrong usage of mutex warning:

Mutex currently locked (in reverse order):
LOCK_thd_kill /home/sciascid/Workspace/src/mariadb-server/sql/sql_class.cc line 2202
LOCK_thd_kill /home/sciascid/Workspace/src/mariadb-server/sql/service_wsrep.cc line 42

This should disappear after https://github.com/MariaDB/server/pull/1900 merged.

This no longer reproduces. Tested on 10.4 and 10.5. Will submit a pull request to re-enable the test on 10.5.
However, the problem still persists with MDEV-28460, which initially seemed to duplicate this one.
