Bug #29536: timestamp inconsistent in replication around 1970

Browse Source 
MySQL replicates the time zone only when operations that involve
it are performed. This is controlled by a flag. But this flag
is set only on successful operation.
The flag must be set also when there is an error that involves
a timezone (so the master would replicate the error to the slaves). 

Fixed by moving the setting of the flag before the operation
(so it apples to errors as well).
