Can not set wsrep_desync to ON, OFF, only to TRUE, FALSE

[Philip Stoev]

ON and OFF are not valid values for wsrep_desync , even though they are mentioned in presentations and the Percona documentation.

TRUE and FALSE work.

MySQL [test]> SET GLOBAL wsrep_desync = ON;
ERROR 1396 (HY000): Operation 'desync' failed for SET GLOBAL wsrep_desync = ON
MySQL [test]> SET GLOBAL wsrep_desync = OFF;
Query OK, 0 rows affected, 1 warning (0.01 sec)
