Bug#17284 erroneous temp table cleanup on slave.
Idea of the fix is for master to send FD event with `created' as 0
to reconnecting slave (upon slave_net_timeout, no master crash) to avoid destroying temp tables.
In a case of a connect by slave to the master after its crash temp tables have been already
cleaned up so that slave can not keep `orphan' temp tables.
