Shared/Database: Fix transactions not being recommitted on dead-lock error

Browse Source 
Fix transactions not being recommitted on dead-lock error (error code 1213) because of calling http://dev.mysql.com/doc/refman/5.0/en/mysql-errno.html after sending the ROLLBACK command. This way the returned error code was related to the ROLLBACK command, not the failed transaction.

(cherry picked from commit d4db0c15c7)
